摘　　要：2004年的研究结果表明,黑龙江省东部地区小麦白粉病菌群体中,V1、V3a、V3b、V3c、V3f、V5、V5(Mli)、V6、V7和V8频率较高(>93.6%);而V2、V4a、V21、V5+6、V2+Talent、V2+Mid、V2+6频率较低(<17.7%)。与以往的研究结果比较,该地区与本省其它地区的小麦白粉病菌群体结构基本相同。The virulent genes of wheat powdery mildew （ Erysiphe graminis f. sp. Tritici ） were studied in eastern region of Heilongjiang province in 2004. The result showed that the virulent frequency of V1, V3a, V3b, V3e, V3f, VS, VS（Mli）, V6, V7, V8 was high （〉93.6%）; but that of V2,V4a,V21,VS＋6,V2＋Talent,V2＋Mid,V2＋6 was very low （〈17.7%）. Similar structures of the mildew populations were found in different regions of Heilongjiang province were found.
