摘　　要：对在黑龙江省建三江农场、佳木斯、黑河、鸡西、双鸭山、宾县、双城、阿城、巴彦、宁安、海伦、绥化、宝清、延寿采集的具有典型病症的262份病株,用病组织法共分离出60个菌株,鉴定出1号、3号、15号、17号4个生理小种,病原菌可以划分为16个毒性类型,其中有12种毒力型为中间类型,表明分离到病原菌菌株具有十分复杂的毒性类型。60%的菌株为1号生理小种,证明1号小种为黑龙江省的流行优势生理小种,15号生理小种在中国首次被报道。60 strains of Phytophthora sojae have been isolated from 262 infected plants collected from Jiansan-jiang Farm, Jiamusi, Heihe, Jixi, Shuangyashan, Binxian, Shuangcheng, Acheng, Bayan, Ningan, Hailun, Suihua, Baoqing,Yanshou in Heilongjiang Province. Racel, 3,5 and 17 have been identified. The total number of virulence types was 16, and there are 12 intermediate virulence types among them, which showed that these strains were very complex in virulence. 60% of all collected plants were infected by race 1 which appeares as the dominant race in Heilongjiang Province. Race 15 was reported for the first time in China.
