A. Wheat in Ethiopia (2009)

Cereals are 1st in area and volume of production

Area: 80.3% ~ 9.23 million hectares

A. Wheat in Ethiopia (cont’d)Total area of production, yield ha-1 and total

grain yield of the major cereal crops in Ethiopia (2009)

Crop Area (‘000000 ha)

IMPORTANT CONSTRAINTS OF WHEAT PRODUCTION

Many technical and socio-economic constraints

Problems depend on agro-ecology, demands of the wheat producers and consumers

A) Unavailability of improved cultivars for different agro-ecologies

B) Slow extension of available improved cultivarsIneffectiveness of formal and informal seed

sector/sources

IMPORTANT CONSTRAINTS OF WHEAT PRODUCTION (cont’d)

C) Disease pressure

Head scab

stemrust

Septoria

Yellowrust

Approximate areas affected by stripe rust , 2010

IMPORTANT CONSTRAINTS OF WHEAT PRODUCTION (cont’d)

D) Quality

E) High input prices (major concern of wheat growers)

F) water-logging (~12 million ha)

G) Characterization and grouping of L and G for

maximum exploitation of the wheat

environmentsYield gap (5-6 tons)

Approaches of breeding:

Conventional and participatory (Molecular ??)

Multi-location variety trials :Many agro-ecological zones ( eg. 10

representing testing sites in NWE)Plus more than 20 on-farm sites (FREGs)

for participatory VT and agronomic trials

Participatory variety selections –PVS (Farmers, extension agents and other research disciplines)

Variety testing (on-farm)

20 varieties1st year

Pre-verification 3-5 vars 2ndyear

Verification for release 3 cultivars 3rd year
