Wheat Breeding in North western Ethiopia
“Wheat Science to text books” workshopCIMMYT, Texcoco, Mexico
December 5-11, 2010

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)
% Area
Yield (Q ha-1)
Total yield (‘000000 Q)
Tef 2.58 (1st) 22.5 12.28 31.79 (2nd)
Maize 1.77 (2nd) 15.4 21.99 (1st) 38.97 (1st)
Wheat 1.68 (3rd) 14.64 18.27 (3rd) 30.76 (3rd)
Sorghum 1.62 14.07 18.36 (2nd) 29.71
Barley 1.13 15.5 17.5

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
Seed prodn
1-3 vars4th year
