对黑龙江省不同地区的Blumeria graminis DC.Speer的毒力基因和频率进行了研究。结果表明，黑龙江省发现了Blumeria graminis DC.Speer的毒力基因和频率。V0、V1、V3a、V3b、V3c、V3f、VS、VS(Mli)、V7和V8为强毒力。 V2、V5+6、V2+Talent、V2+Mid、V2+6毒力频率较低，抗性基因Pm2、Pro5+6、Pm2+Talent、Pm2+Mid、Pm2+6可作为小麦白粉病育种的抗性资源。
The virulent genes and frequency of Blumeria graminis DC.Speer in different regions of Heilongjiang province were studied.The results showed that the similar structures of Blumeria gra- minis DC.Speer were found in Heilongjiang province.V0,V1,V3a,V3b,V3c,V3f,VS,VS(Mli), V7 and V8 were virulent genes.V2,V5+6,V2+Talent,V2+Mid and V2+6 were lower in virulent frequency,so the resistant genes Pm2,Pro5+6,Pm2+Talent,Pm2+Mid and Pm2+6 could be used as resistant resources of wheat powdery mildew breeding.
