采用菌液注射法，以来源于山东青岛、云南双龙和陕西太白的大白菜根肿病菌为病原菌，对49个抗根肿病大白菜品种进行人工接种抗病性鉴定。结果表明：参试49个大白菜品种对3个地区根肿病菌存在抗性差异，其中32个品种对山东青岛根肿病菌和陕西太白根肿病菌抗性表现基本一致，推测这两地的生理小种一致；云南双龙根肿病菌与山东青岛、陕西太白根肿病菌为明显不同的生理小种，且致病力强、抗源少。
採用菌液註射法，以來源于山東青島、雲南雙龍和陝西太白的大白菜根腫病菌為病原菌，對49箇抗根腫病大白菜品種進行人工接種抗病性鑒定。結果錶明：參試49箇大白菜品種對3箇地區根腫病菌存在抗性差異，其中32箇品種對山東青島根腫病菌和陝西太白根腫病菌抗性錶現基本一緻，推測這兩地的生理小種一緻；雲南雙龍根腫病菌與山東青島、陝西太白根腫病菌為明顯不同的生理小種，且緻病力彊、抗源少。

s:Plasmodiophora brassicaeof Chinese cabbage from Qingdao in Shandong Province,Shuanglong in Yunnan Province,and Taibai in Shaanxi Province were innoculated to 49 Clubroot Resistant(CR)Chinese cabbage varieties to carry out identification.The results showed that the Chinese cabbage varieties’resistances toPlasmodiophora brassicae from3above locations weredifferent.32 varieties had the same resistance toPlasmodiophora brassicaefrom Qingdao in Shandong Province,and Taibai in Shaanxi Province.We speculated that the physiological races from these 2 locations were the same.Plasmodiophora brassicaefrom Shuanglong in Yunnan Province was physiological race distinctively different from that of Qingdao in Shandong Province and Taibai in Shaanxi Province.Plasmodiophora brassicaefrom Shuanglong in Yunnan Province had strong pathogenicity,and less resistant resource.
