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.
