摘　　要：采用温室人工接种和田间病圃自然诱发鉴定方法,对湖南近年栽培的100个油菜品种进行抗根肿病鉴定。结果表明,100个油菜品种对根肿病的抗性存在差异,即便同一品种对不同地区的根肿病菌的抗性表现也有所不同;温室人工接种时,有57个油菜品种表现抗根肿病;在沅陵和衡阳病圃田间自然诱发抗性鉴定中,分别有45个和8个表现抗病。综合温室和田间病圃抗性鉴定结果,有7个油菜品种表现抗病,即亮景811、中研油1号、华信402、沣油737、宝油150、油研九号和嘉油1427。The resistance to Plasmodiophora brassicae(P. brassicae) of 100 rapeseed varieties cultivated in Hunan Province in recent years was evaluated by artificial inoculation in greenhouse and natural induction. Results showed that 57 cultivars were resistant to P. brassicae when estimated by artificially inoculation in greenhouse. Among the 100cultivars in Yuanling and Hengyang, there were 45 and 8 resistant cultivars in the two regions, respectively. Combined the results of greenhouse and field resistance identification, 7 resistant rapeseed cultivars were identified, including Liangjing811, Zhongyanyou1, Huaxin402, Fengyou737, Baoyou150, Youyan9 and Jiayou1427.
