摘要： In order to know population structure of M. grisea from Fujian province of China, pathogenicity of M. grisea single spore isolates isolated from Fujian Province in recent years was analyzed on 3 sets of differential rice varieties. The analysis showedthat 97 of 300 isolates could be differentiated into 15, 14 and 22 pathogenic types by the Chinese rice differentials, CO39 near-isogenic lines (NILs) and LTH NILs. The dominant pathogenic types were ZB13,134.1 and J76.2 that occurred in frequencies of55.7%, 52.6% and 28.9%, respectively. The pathogenic types ZB14,135.1 and J72.2 were less dominant and occurred at frequencies of 13.4%, 22.7% and 14.4%, respectively.
