摘　　要：对2007—2010年小麦白粉病菌的生理小种类型、小种动态变化进行研究。结果表明:白粉病菌小种种群结构复杂,共鉴定出36个生理小种,优势小种分别为31号、111号、311号生理小种,出现频率分别为27.27%、27.27%、26.19%,其次为11号、115号和401号小种。同时小麦白粉病菌具有低毒力小种锐减、中毒力和高毒力小种增加的变化趋势。The race types and dynamic change analysis on Blumeria graminis（DC.）Speer f.sp.tritici in 2007—2010 were studied.The results showed that Blumeria graminis（DC.）Speer f.sp.tritici had complex structure.36 races were identified and the most common race were No.31,111 and 311,respectively.Their occurrence frequencies were 27.27%,22.27% and 26.19%,respectively.No.11,115 and 401 were following.At the same time,the weak virulent races of Blumeria graminis（DC.）Speer f.sp.tritici had a sharp declin,the moderate and the strong virulent races of Blumeria graminis（DC.）Speer f.sp.tritici had an increaseing tendency.
