Abstract 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 clubroot. 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 Country, Wula Street Old Street Country,Pear Town, the eleven areas clubroot are the 4 physiology race; Liaoning Benxi area clubroot is the 2 physiology race; Sichuan Peng state area clubroot is the 7 physiology race; Sichuan Xichang area clubroot is the 10 physiology race; Shenyang Agricultural University area clubroot is the 11 physiology race.
