2006～2007年在黑龙江省各主要大豆产区采集并分离大豆灰斑病菌菌株210个,采用一套鉴别寄主对采集的大豆灰斑病菌进行鉴定,结果表明:黑龙江省大豆灰斑病菌共有16个生理小种,除以往报道的1～4号、6～11号生理小种外,又增加了5号、12～16号等6个新的生理小种.从主要生理小种在黑龙江省内各地的出现频率来看,以1号小种出现频率最高,为41.43%,其次是7号小种,为13.33%,10号小种出现频率为6.67%,占第三位.黑龙江省内大豆种植区主要以1号小种占优势,各地小种的组成和比例均有所不同.

210 isolates of soybean frogeye fungus (Cercospora sojini) were collected from Heilongjiang province during the year of 2006 to 2007.They belonged to 16 physiologic races identified using 6 differential soybean varieties.There were 6 newly found physiologic races including No.5,No.12,No.13,No.14,No.15 and No.16,and other 10 physiologic races (No.1 to 4 and No.6 to 11) were reported before.The most frequently appreared three races were No.1 (41.43%),No.7 (13.33%) and No.10 (6.67%).Although race No.1 was dominant in the soybean areas of Heilongjiang province,types and compositions of the races were different from place to place.
