用日本9个水稻单基因鉴别品种和BL1、K59两个参考品种鉴定了云南省4个稻作区21个县(市)采集、分离的155个稻瘟病菌单孢菌株，结果出现78个稻瘟病菌生理小种，其中优势小种为136.4(出现频率为6.5%)、317.4(出现频率5.2%)、007(出现频率5.2%)小种。通过研究各稻作区生理小种对日本鉴别品种的侵染率，分析了各垂直抗性基因在不同稻作区的利用价值。

It reports the result of 155 Magnaporthe grisea Cavara single-cell races collected and isolated from 21 counties in 4 rice growing regions of Yunnan Province were identified using 9 single-gene differential varieties and 2 reference varieties, “BL1” and “K59” from Japan during 1993-1997. It was divided 78 races, and the dominants were 136.4, 317.4, and 007. Meanwhile the races among four counties were compared and the availability of each vertical resistant gene was assessed by analysing infection frequency in different rice growing regions.
