摘要
对采自黑龙江省、吉林省的42株大豆疫霉根腐病菌进行生理小种鉴定,其中11株可被分别鉴定为1号、3号和8号生理小种。1号小种为优势小种,3号、8号小种为国内首次报道。其余31株在鉴别寄主上出现中间类型反应无法鉴定小种,但可以划分为12个毒性类型,病原菌群体具有很高的毒性多态性,其中有些菌株毒性较强。
42 isolates of P. sojae obtained from Heilongjiang Province and Jilin Province were identified for their physiological races. 11 isolates were classified into 3 races - races 1, 3 and 8. Race 1 was the relatively prevalent race, and races 3 and 8 were identified for the first time in China. The other 31 isolates that could not be classified due to intermediate reactions were classified into 12 virulence types, suggesting that the tested pathogen had great diversity in virulence. Some isolates were very virulent on the tested Rps.
