| 摘 要： | 42 isolates of P. sojae were obtained from diseased soybean plants in 9 counties of Heilongjiang Province and 1 county of Jilin Province in Northeast of China. 11 isolates were classified into 3 races ;the rest that could not be classified due to intermediate reactions were classified into 12 virulence types, suggesting virulence diversity of P. sojae in China. Isolates represented race 1,3 and 8. Race 1 was the most prevalent one.and races 3 and 8 were the first report in China. Our results suggest P. sojae is aboriginal in China.
