摘　　要：采用Williams法的4个鉴别寄主(Jersey Queen、Badger Shipper、Laurentian、Wilhelmsburger)对采自国内15个大白菜根肿病主要发病区域的病原菌进行了生理小种种群鉴定。结果表明:辽宁沈阳新民大民屯、辽宁沈阳西窑、辽宁大连水师营、辽宁丹东振安、山东青岛农业科学院、山东苍山小林村、云南江川、四川郫县、吉林乌拉街东窑村、吉林乌拉街旧街村、吉林梨树镇11个地区的根肿病菌主要种群为4号生理小种;辽宁本溪桓仁地区的根肿病菌为2号生理小种;四川彭州地区的根肿病菌为7号生理小种;四川西昌地区的根肿病菌为10号生理小种;辽宁沈阳农业大学的根肿病菌为11号生理小种。This experiment uses 4 specific antigens of Williams. A system （‘Jersey Queen＇,‘Badger Shipper＇ ,‘Laurentian＇ ,‘Wilhelmsburger＇ ） to identify main physiological races of pathogens from 15 domestic main disease regions of Chinese cabbage elubroot. The result indicated that, the clubroot pathogen in Liaoning Shenyang Xinmin Damintun, Liaoning Shenyang Xiyao, Liaoning Dalian Shuishiying, Liaoning Dandong Zhen＇an, Shandong Qingdao Academy of Agricultural Sciences, Shandong Cangshan Xiaolin Village, Yunnan Jiangchuan, Sichuan Bi County, Jilin Wula Street Dongyao Village, Jilin Wula Street Jiujie Village, Jilin Lishu Town, the main population of these 11 are No. 4 physiological race. In Liaoning Benxi Huanren region is No. 2 physiological race. In Sichuan Pengzhou region is No. 7 physiological race. In Sichuan Xichang region is No. 10 physiological race. In Liaoning Shenyang Agricultural University is No. 11 physiological race.
