and winter ~ere favorable bu~ the spring months w~re very clry ~eserve Boil moisture carried the crop well until mid-May when drought symPtoms~ppeared Little growth occurred between May 15 and June 7 when good rains broke the drought Although plants were very short all varieties in the nursery exceeded 40 bushels in yield

Springfield--The May 12 freeze overshadowed all other pr~du~t~on factors at Springfield in 1966bull Atthe onset of spring the conditio 01 the nursery was such that it held promise ppound being the best at the station iomany years The freeze damaged all varieties but was particularly severe inthe early maturing ones

Yellow Jacket--This also is a new testing site iri Colorado It replaces t~e nursery formerly grown at H~sperusand better represents the wheat producshytionarea of western Colorado than did Hesperus Th~ nursery was not seeded until October 29 due to wet weather Stands were only fair and little fall growth occurredbullThere wa~ nowinterkiiling The sPfIng a~dearly~ummer were cool and moisture adequate until fruiting when th~ ffrst drought stress symptoms w~re noted Secondary tillers of sqme varietielffail~dtodeve~op

Summary ~ Nursery Yields

Individual station yields made by vari~ties in the southern regional pershyformance nursery in 1966 a1ongwith their average state yields and ranks and regional averages are shown tn table 2 Varieties are arranged according to their regional average yields~ The broad adapt~tion of Scout was again evident Its average yie1dof 38~2 bushels per acre was high for the nursery C I 13888 and C I 13996 yielded almost as much as Scout with averages of 379 and 375 bushels Next were C I 13886 C I 13856 and OK627514 all with yields higher than 36 bushels per acre The poorest regional performance was recorded for C L 13850 Its average yield of 295 bushels was nearly one bushel below that of Iltharkofthe latest maturing variety among those tested The Scout Selections C I~ 13996 and C I 13886 have the best 2-year average yields both above 40 bushels per acre (table 3) The pOQrest 2-year average yield among varieties tested in both 1965 and 1966 was recorded for the semi-dwarf varie ty Sturdy

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Sherldail--Growing conditions were better atSheridan than at Archer although dry weather in the $pringr~duced the height~nd yields There was no lodging anq diseases were not ~ factomiddotr in the yields reported Yield difshyferences were not s~atisticaUYsignifLcantmiddotbull

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary ~ Nursery Yields

Individual station yields made by vari~ties in the southern regional pershyformance nursery in 1966 a1ongwith their average state yields and ranks and regional averages are shown tn table 2 Varieties are arranged according to their regional average yields~ The broad adapt~tion of Scout was again evident Its average yie1dof 38~2 bushels per acre was high for the nursery C I 13888 and C I 13996 yielded almost as much as Scout with averages of 379 and 375 bushels Next were C I 13886 C I 13856 and OK627514 all with yields higher than 36 bushels per acre The poorest regional performance was recorded for C L 13850 Its average yield of 295 bushels was nearly one bushel below that of Iltharkofthe latest maturing variety among those tested The Scout Selections C I~ 13996 and C I 13886 have the best 2-year average yields both above 40 bushels per acre (table 3) The pOQrest 2-year average yield among varieties tested in both 1965 and 1966 was recorded for the semi-dwarf varie ty Sturdy

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Nebraska Stations--Replicated nurseries Jere grown at North Platte and Alliance Single rod-r~w plots for observation auddisease reading~ only were grown at Lincoln Growirig conditions at the Nebraska locations are discussed in connection with the southern regional performance nursery Extremely high yields were recorded at North Platte where only one entry yielded less than 50 bushels per acre and 9 entries exceeded 60 bushels At Alliance where the spring drought was more severe nursery yields were in the 20 to 40 bushel range

Archer--Good fall stands were obtained at Archer and all varieties survived the winter well Droughty conditions prevailed throughout the spring resulting in very short straw and low yields Only one variety in the nursery exceeded 20 bushels per acre and one produced less than 10 bushels

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Waseca--Fall winter and spring conditions at Waseca were very similar to those at St Paul Stand losses during the winter were somewhat greater than at St Paul but not severe The straw was taller and grain yields were 10-20 bushels higher at Waseca

Dickinson--Varieties in the northern regional performance nursery escaped the winter with a minimum of stand loss Differences in spring stands probashybly reflect variable fall stands as well as stand losses during the winter Generally favorable conditions prevailed during the spring Both stem and leaf rust developed at Dickinson but too late to cause measurable damage Timely moisture late in the season probably favored the later maturing varishyeties in the nursery Kharkof was the most productive followed by C I 13993 Cheyenne and C I 13995 in that order

Williston--This was the first year the nursery was grown at Williston Fall stands were variable and winterkilling although spotty throughout the nursery appeared to be a factor in varietal performance Plot size will be enlarged for 1967 to accommodate the use of a large drill in the nursery seeding operation Varieties with the highest winter survival tended to be the most productive C I 13993 Winalta Cheyenne and Kharkof yielded more than 30 bushels per acre Bushel weight was less than 60 pounds for all varieties the lowest being 556 pounds for Kharkof No leaf or stem rust was observed

Moccasin--The northern regional nursery was transferred from Havre to Moccasin in 1966 It will be grown at the latter station henceforth Unshyusually good conditions for winter wheat prevailed throughout tbe fall and winter at Moccasin There was little effective moisture during the spring and early summer but moderate temperatures and reserve moisture permitted varieties to fill and mature well and very high nursery yields resulted Seven varieties exceeded 40 bushels per acre in yield and the lowest yield in the nursery was 30 bushels The lowest bushel weight was 62 pounds with the high being 646 pounds made by 2 varieties

Tetonia--The nursery survived the winter in exceUie~t condl~ion at Tetonia Prospects for very high yields were all but elim[natedby several freezesili late spring that produced as much as 80 percent head st~rility among th~ earlier maturing varieties NB64323 although 30 percent sterile was slightlytheUi j

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

Summary pound Nurspoundy Yields

Yields of varieties in the northern regional performance nursery in 1966 are summarized in table 6 State averages and ranks together with individual station yields and regional averages are shown Warrior x Selkirk-Cheyenne2 (NB64323) ranked first on a regional basis with a 388-bushel average yield Cheyenne Selkirk x Cheyenne 2 (NB64365) Warrior Warrior x Selkirk-Cheyenne4 (NB64322) and Lancer in that order were next highest in yield No variety was consistently high in yield in all states NB64323 ranked first in Wyoming Minnesota and Idaho third in Montana and at Lethbridge_fQ1J~th_fiLClovissixth in Nebraska but only twelfth in South Dakota and fiftemiddotithi~_North Bakota Perhaps the most consistent performer was Cheyennemiddot~injltiiigmiddot no poorerthan ninth in any state except at Lethbridge where its rankmiddot~ks sixteenth Lessthan 10 bushels per acre separated the highest and lowestmiddot yiiiJtng entries in the nursery Yields made by varieties in 1966 are of particular interest since at no station were the rusts a factor in performance and winterkilling was recorded at only 4 out of 14 stations This years yields probably reflect the range of adaptashytion or elasticity of varieties to a much greater degree than in most years when the rusts depress yields differentially according to the res1stance and maturity of varieties In 1966 stem rust resistance or early maturity provided no particushylar advantage to varieties

Among those varieties grown in both 1965 and 1966 in the northern nursery Lancer has the best record with a 365-bushel average yield (table 7) This is 26 bushels higher than C I 13883 the second ranked variety Despite their excellent performance in 1966 when stem rust was not a factor the suscepshytible varieties Cheyenne and Warrior have only fair 2-year average yields due to their relatively poor performance in 1965 when stem rust was a factor at most stations In contrast Lancer with resistance to stem rust ranked first in yield in 1965 and sixth in 1966

Summary pound Agronomic Data

Agronomic data for varieties are summarized in table 8 Highest average bushel weight (615 pounds) was recorded for Winalta C I l3884and NB64365 Only 2 varieties C 1 13994 and KS60252had average bushel weights of less than 60 pounds LancerC 1 13882 and KS60252 headed the earliest but SD56-497 had the earliest average ripe date Lancer SD55 and Warrior were among the shortest strawed varieties while C I ~3858 had the tallest straw C 1 13995 survived the best at 4 stations where differentialmiddot winterki1ling was recorded C 113864 had the lowest average surviva~ $D56-497 lodged the least at 2 reporting stations while C I l38ff5 lodged most ~

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races

UNIFORM BUNT NURSERY

Five of 8 stationsamprowing the uniform bunt nursery in 1966 reported inshyfection data Theke aresurinnarized in table 9 together with data from the Cereal Disease La~ratory at Pullman Washington Only the check variety Wasatch was re~istant at all reporting stations Hussar and C I 13882 were rated resistant a~ all stations except Stillwater The presence of L~8 in the inoculum at Ft Collins and Stillwater is indicatedby the susceptibility of Oro and T~rkey derivatives at those stations--an exception being C I 13882 at Ft Collins~ The susceptibility of both Hussar and Relief at Stillshywater suggests the presence of L-7 in the inoculum at Stillwater

The unif~rm bu~tnurseryhasbeen discontinu~d as a field nursery in the hard red wiJlter wheat region Henceforth varietteswith resistance to bunt in state nurseries will be submitted to the Cereal-Disease Laboratory at Pullshyman for reac~ionto specific ~unt tester races
