摘　　要：为探究湖南现有白菜栽培品种对根肿病的抗性,分别采用田间自然诱发鉴定、温室和组织培养室内人工接种鉴定等3种方法,对50个白菜品种(另设感病和抗病对照品种各1个)进行了抗性鉴定。结果表明:50个参试栽培品种对根肿病的抗性存在明显差异,经3种方法鉴定均表现高抗的品种有7个,即矮脚小白菜、矮脚白、油青甜菜心、秋绿60、汕头甜白菜、中箕青菜605、德高富贵,占参试品种的14%;抗病品种7个,占14%;耐病品种3个,占6%;感病品种20个,占40%;有13个品种在3种鉴定方法中抗感表现不一致。The resistances of 50 Chinese cabbage varieties planted in Hunan against the clubroot disease that naturally occurred in fields or induced by artificial inoculation at seeding stage in greenhouse and tissue culture room were investigated with one resistant variety and one susceptible variety as controls. The results showed that there was obvious difference among the tested Chinese cabbage varieties in their ability to resist clubroot disease. Seven varieties, accounting for 14%, that is Aijiaoxiaobaicai, Aijiaobai, Youqingtiancaixin, Qiulv60, Shantoutianbaicai, Zhongqiqingcai 605 and Degaofugui, were highly resistant to clubroot disease; seven varieties, accounting for 14%, were resistant to clubroot disease; three varieties, accounting for 6%, were tolerant to clubroot disease; and 20 varieties, accounting for 40%, were susceptible to clubroot disease as identified both by natural and artificial methods. But for the remaining 13 varieties, the resistances identified by natural methods were not consistent to those by artificial method.
