• Base on our national rust surveillance in 2002 (Virulence for Yr27) in South & West of IRAN (Fars and Kermanshah).
• Test of wheat genetic materials in Zarghan was done.
• Over last 3 years 10 resistance wheat Cvs. for different climate of Iran are released.
Conclusion remarks
• It is importance to do Rust surveillance, race analysis, molecular genetic diversity at national and regional levels
• Using GIS, preparing crop calendar for targeted regions
•Searching for new sources of resistance genes and building up the genetic basis of resistance
• Timely communication and exchange data among the rust networks
•Regional traveling workshops and special training on rust monitoring
• Breeding for high yielding resistant cultivars
• Replacing susceptible cultivars with resistance
Thank You
