摘　　要：采用Williams鉴别系统的4个鉴别寄主(2个芜菁甘蓝品种Laurentian和Wilhelmsburger,2个结球甘蓝品种Jersey Queen和Badger Shipper),于2011—2012年连续2年对采自黑龙江、吉林、辽宁的11个大白菜根肿病主要发病区域的病原菌进行了生理小种鉴定。结果表明,东北地区大白菜根肿病菌主要种群均为4号生理小种。From 2011 to 2012, 4 identification hosts in Williams system （two types of Brassica napus L. Laurentian., Wilhelmsburger and two types of Brassica oleracea L.Jersey Queen., Badger Shipper.,） were used to identify the physiological races of pathogens causing club root in 11 regions of Heilongjiang, Jilin and Liaoning provinces where club root diseases of Chinese cabbage were mainly occurred. The result indicated that all strains of pathogens from the 11 regions were race 4.
