One thousand and thirty two monoconidial isolates of M. grisea collected from Jiangsu Province, China, during 1980-1996 were classified into 8 groups and 22 races by assessment on 7 Chinese differential rice varieties. The predominant race during this time was ZG1, except in 1990 and 1991, when it was replaced by group ZA + group ZD, and ZE respectively. The frequency of race ZG1 was as high as 66.20%, and was stable among most of the years monitored.
