The resistance material WP6192 to Blumeria graminis f.sp.tritici is derived from the cross of Triticum polonicum×Zhong 13.It was highly resistant to the powdery mildew in field trials.Genetic analysis of resistance to powdery mildew indicated that the resistance was controlled by a single dominant gene.The gene was temporarily designated as PmWP6192.By bulk segregation analysis,microsatellite markers including Xgwm515,Xgwm249,Xgwm425,Xgwm372,Xgwm630,Xbarc10,Xbarc220,Xbarc201 and Xbarc353 were found to be linked to PmWP6192.The nearest marker with PmWP6192 is Xbarc353 with genetic distances of 2.3 cM.According to the chromosomal locations of the linked markers,the resistance gene was located in the 2AL region.Based on its origin and allelism test using molecular markers have been linked to powdery mildew resistance gene on chromosome 2AL,PmWP6192 might be a novel resistance gene to powdery mildew.
