摘要
2002-2012年从吉林省各水稻栽培区采集了水稻稻瘟病标样1463份。分离获得936个单孢菌株，用7个全国统一稻瘟病菌鉴别品种进行鉴定，鉴定出7群43个生理小种。优势种群为ZE群和ZG群，次要种群为ZF群；优势小种为ZE1和ZG1，频率为22．65％和21．79％，次要小种为ZF1，出现频率为13．25％。两个优势小种在不同地区占有绝对优势。但又存在着明显差异。
936 mono-spore strains were separated from 1463 samples of rice blast collected from each paddy rice production fields in Jilin province from 2002 to 2012. They were identified by seven Chinese rice cultivars and classified into 7 groups and 43 races. ZE and ZG groups were dominant groups, ZF group was secondary group. ZE1 and ZG1 were dominant physiological races, which emergence rates were 22.65% and 21.79%. ZF1 was secondary physiological race, which emergence rate was 13.25%. Two dominant races in different regions had an absolute advantage, but there were obvious differences.
