摘　　要：经对黑龙江省不同地区小麦白粉病菌毒性结构和毒力频率研究表明,黑龙江省小麦白粉病菌具有基本相同的群体结构,其中V0、V1、V3a、V3b、V3c、V3f、V5、V5(Mli)、V7、V8为黑龙江省小麦白粉病菌的毒性基因,而V2、V5+6、V2+Talent、V2+Mid、V2+6毒力频率较低,因此,与之相对应的抗性基因Pm2、Pm5+6、Pm2+Talent、Pm2+Mid、Pm2+6,可作为黑龙江省抗小麦白粉病育种的抗源。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 graminis DC. Speer were found in Heilongjiang province. V0, V1, V3a, V3b, V3c, V3f, VS, V5 （M/i）, 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, PmS＋6, Pm2＋Talent, Pm2＋Mid and Pm2＋6 could be used as resistant resources of wheat powdery mildew breeding.
