Abstract
Wheat powdery mildew caused by Blumeria graminis f.sp. tritici is one of the most common diseases in cool and humid regions. Awareness of fungal variability is necessary to manage disease specially due to using new lines and cultivars. This study was conducted to detect virulence factors of Blumeria graminis f.sp. tritici using trap nurseries in natural conditions in Gorgan, Mazandaran, Moghan and Varamin regions during 2005-2007. The experiments were carried out using 17 near isogenic lines/cultivars carrying Pm resistance genes received from Germany. The experiments were based on RCBD with three replications in each region. The reaction of the cultivars to B. graminis f.sp. tritici were recorded at booting stage and two weeks later based on scale 0-9. The results of three years study showed that cultivars MARIS HUNTSMAN (Pm2+6), APOLLO (Pm2+4b+8) and RALLE (Pm3d) were highly resistant in all regions and cultivars RONSO(Pm4b), REKTOR(Pm5) and NK-747 (Pm6) were relatively resistant. These cultivars have potential to be incorporated into high yielding commercial wheat cultivars in Iran
