Arrino ASWN InterGrain 1997 Short-Mid Yes Free to trade

$0.00

Comment: Eradu background. ASWN for low rainfall areas and later sowings. Recently released ASWN variety (Supreme) has better rust resistance package. Strengths: Moderately resistant to Powdery mildew. Risks: Low falling number index (2) and susceptible (S) to very susceptible (SVS) to Stem rust. Susceptible to Leaf rust, Stripe rust and RLN (P. quasitereoides and P. Neglectus).

Bonnie Rock A AH InterGrain 2002 Short Yes# Free to trade

$2.50

Comments: Also known as EGA Bonnie Rock. Aroona background. Recommended in Agzone 1 & 4 because of rust package. Intermediate sensitivity to frost. Strengths: Low risk for black point. Risks: Very susceptible (VS) to stripe rust, 'S' to Leaf rust, Powdery mildew, Flag smut, RLN (P. quasitereoides and P. Neglectus) and CCN. Stem rust resistance level has been downgraded to moderately susceptible to susceptible (MSS). 'S' to Septoria tritici blotch.

Bremer A AH AGT 2015 Mid Yes AGT affiliates

$3.25

Comments: An AH variety for med to high rainfall areas. Strengths: Good rust package with Stripe Rust -moderately resistant (MR*), Stem Rust - resistant to moderately resistant (RMR) and Leaf Rust (MR). Low screenings. Maintains falling number after pre harvest rain (5p*), similar to Yitpi. Risks: 'S' to Septoria tritici blotch, Powdery mildew, Flag smut and Crown rot. Maturity like Magenta so not suited to low rainfall areas/later plantings.

Calingiri ASWN InterGrain 1997 Long Yes Free to trade

Comments: Kulin and Reeves background. Strengths: ASWN wheat for earlier sowings. Less sensitive to frost (similar to Yitpi). Risks: 'S' to current strain of Stem and Stripe rust, Powdery mildew, RLN (P. quasitereoides) Crown Rot and Septoria tritici blotch. 'SVS' to P. Neglectus.

Cobra A AH LPB 2011 Short-Mid Yes# Associate (PacSeeds)

$3.50

Comments: Westonia background. Intermediate frost sensitivity. Strengths: Yielded well in NVT’s grown on acid soils. Performs well in high yielding environment. Stem rust -RMR and Leaf rust - 'MR'. Risks: Susceptible to low falling numbers after pre harvest rain (2p), risks if adopted for the south coast. Crown Rot - 'S'.

Corack A APW AGT 2011 Short-Mid Yes AGT affiliates

$3.00

Comments: Wyalkatchem background. Suited to late May, early June sowing. Strengths: Useful resistance to CCN (RMR) and stem rust (MR). Risks: Powdery mildew -'SVS', Black Point (MSS), Septoria tritici blotch and Crown Rot are 'S'. Now 'S' to Leaf rust. Corack is less suitable to higher rainfall zones because of its susceptibility to Black Point and Leaf rust. Sensitive to frost (Wyalkatchem equivalent).

Cutlass A APW AGT 2015 Mid-Late Yes AGT affiliates

$3.00

Comments: Recently released. Later maturity, similar to Yitpi but APW classification. Strengths: 'R' to Stem rust. 'RMR' to Stripe rust and Leaf rust. 'MSS' to Yellow spot (compared to Yitpi's 'SVS'). Risks: Slightly less tolerant to sprouting than Yitpi.

Low falling number rating after pre harvest rainfall (2p).

Justica CL Plus A APW-imi

AGT 2011 Mid-Long No AGT affiliates

$3.55

Comments: Spear background with two imi-tolerance genes. AGT have suggested a switch recently released Grenade CL which has a better disease package and quality traits. Intermediate frost sensitivity.

Mace A AH AGT 2008 Short-Mid Yes^ AGT affiliates

$3.00

Comments: Wyalkatchem background with higher grain yields. The benchmark variety for yield in WA. Wide adaptation across regions and soil types. Intermediate sensitivity to frost. Strengths: Better disease resistance than Wyalkatchem. Superior to Wyalkatchem for falling number after pre harvest rain. Boron tolerance. 'MR' to stem rust and Common bunt and 'RMR*' stripe rust. Risks: High yielding so may require increased nitrogen fertilisation to prevent protein dilution. 'S' to Septoria tritici blotch, Flag smut and Crown rot.

Disease ratings

VS = Very susceptible, SVS = Susceptible to very susceptible, S = Susceptible, MSS = Moderately susceptible to

susceptible, MS = Moderately susceptible, MRMS = Moderately resistant to moderately susceptible, MR = Moderately

resistant, RMR = Resistant to moderately resistant, R = Resistant. No score '-' = no rating is currently available. p =

Provisional assessment. / = Scores separated by ‘/’ indicate the response to the 'currently predominant' and 'alternate'

strains of stem rust existing in WA. * = Some races in eastern Australia can attack these varieties. # = May be more

susceptible to the new leaf rust pathotype. ( ) = Higher disease at some sites. Combined RLN ratings from DAFWA,

SARDI (^), DPI Vic and DEEDI data. CCN ratings from SARDI data. Wallwork and Zwer (2016) Cereal Variety

Disease Guide 2016, Factsheet Feb 2016. R=resistant - nematode numbers will decrease when this variety is grown.

MR=moderately resistant - nematode numbers will slightly decrease when this variety is grown. MS=moderately

susceptible - nematode numbers will slightly increase when this variety is grown. S=susceptible - nematode numbers

will increase greatly when this variety is grown. Crown rot ratings from SARDI data 2009-2014 (Butt, Edmondson, and

Wallwork), Qld data 2009-2014 (Bottomley, Herde, Neate, Percy, and Walters) and DPI NSW data 2013-2014
