| Abstract: | 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. |
