摘　　要：2002～2007年在吉林省内各稻作区采集732份稻瘟病标样,分离出568个有效单孢菌株,用7个中国稻瘟病菌鉴别品种鉴定为7群39个小种,优势种群为ZE群和ZG群,其次是ZD群和ZF群;优势小种为ZE1和ZG1,其次是ZF1和ZD1。鉴定结果表明:吉林省稻瘟病菌生理小种以粳型小种为主,而且粳型优势小种在不同年份、不同地区有变化。568 Mono-spore strains were separated from 732 samples of blast collected from each paddy rice production fields in Jilin province from 2002 to 2007. 7 groups with 39 physiological races were identified by comparing with China verified strains, among which ZE and ZG groups were dominant groups, ZD and ZF were secondary groups, ZE1 and ZG1 were dominant physiological races, ZF1 and ZD1 were secondary physiological races. The results showed that japonica physiological race was dominant of blast in Jilin province, and dominant race varied with years and locations.
