IN 2010• EPIDEMIOLOGY OF YELLOW RUST IN 2010• YELLOW RUST RACE ANALYSIS• NATIONAL WHEAT BREEDING ACTIVITY IN 2010• UTILIZED GERMPLSM FOR WHEAT BREEDING
CYCLE IN 2010• RESULTS OF WHEAT BREEDING IN 2010• CONCLUSIONS
Wheat in Tajikistan
• Wheat is a main staple food crop • Bread wheat is growing about 350 000 ha• Production about 650 000 t. in 2009• Average yield is 2.0 -2.2 t/ha.• More than 60% of daily calories for people• Yellow Rust is most important disease
SURVEY AND MONITORING OF YELLOW RUST IN 2010
• Yellow Rust Survey and Monitoring were conducted in main wheat growing areas
• The survey and monitoring were followed by BGRI standardized methodology
• During flowering and milk/dough growing stage (April-May)
• The assessment for severities based on modified Cobb scale (Peterson et al. 1948), and the reaction by Roelfs et al, 1992
• More than 100 wheat fields were surveyed
Surveyed and Monitored Locations in Different Agro Ecological Areas and breeding trials
