In the paper, we identified the physiological races of Plasmodiophora brassicae from twelve clubroot plants of four cruciferous crops, Chinese cabbage (Brassica campestris ssp. chinensis), tuber mustard (Brassica juncea var. tumida), purple flowering stalk (Brassica campestris L. var. purpurea) and rapeseed (Brassica napus) in four different disease areas, Huaihua, Yiyang, Zhuzhou and Changsha, by using the Williams system. The results showed that there were race 1, 4, 9 and 13 in Chinese cabbage, race 1 in tuber mustard, race 4 and 9 in purple flowering stalk, and race 4 and 13 in rapeseed, and there were race 1 and 13 in Chinese cabbage and race 1 in tuber mustard in Huaihua, race 1 in purple flowering stalk in Yiyang, race 4 and 13 in rapeseed in Zhuzhou, and race 9 in both Chinese cabbage and purple flowering stalk in Changsha.
