  • I will discuss three points in my presentation
  • Central Asia included five countries: Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan and Tajikistan
    Caucasus include three countries: Azerbaijan, Armenia and Georgia
  • Many leading winter wheat varieties in Central Asia and the southern Caucasus region are susceptible to stripe rust.
    Stripe rust severity on a few widely grown winter wheat cultivars have been presented here.
  • Our studies in the past two years have shown 28 to 30 grain yield reductions due to stripe rust on widely grown susceptible winter wheat cultivars in Uzbekistan and Tajikistan
  • In last two years, 6 new improved varieties resistant to stripe rust have been submitted in Uzbekistan
    All these varieties originate from IWWIP
    These varieties are expected to replace some of the susceptible varieties occupying large acreages

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
    25. 25. 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
