CRP WHEAT : Partners’ Grant

Additional winter wheat with moderately resistant to stripe rust†

• Azerbaijan: Tale-38

• Georgia: Lomtagora-123, Sauli-9

• Kazakhstan: Egemen, Konditerskaya,

• Kyrgyzstan: Djamin, Zagadka, Petr

• Tajikistan: Alex, Ormon

• Uzbekistan: Dostlik, Yaksart

† There are additional varieties in some countries from nation system

Summary

• Stripe rust resistant winter wheat varieties suitable for Central Asian countries are increasingly becoming available through international collaborations

• Policy emphasis needed on seed multiplication and cultivation of resistant varieties and discourage release and cultivation of susceptible varieties

• Wheat rust research facilities are improving in the Central Asia region, positive development to support international initiative on stripe rust
