摘　　要：十字花科作物根肿病在安徽省黄山市油菜种植区发生日趋严重,已成为限制油菜产量和品质的重要因素。为明确安徽黄山油菜产区根肿菌的生理小种及主栽油菜品种的抗病性,采用Williams法对安徽省黄山市部分地区的根肿病菌进行了生理小种鉴定,采用田间自然发病方法在根肿病发病严重地区对30个油菜品种进行抗性研究。结果表明,目前安徽省黄山油菜根肿病菌为生理小种4号和9号。荃银油5号、德油早1号等品种为抗病品种。这些品种可作为当地根肿病病区主栽品种及育种材料使用。The cruciferous clubroot disease in Anhui Province is increasing year by year. It has become animportant factor limiting canola yield and quality. In this paper, Williams system was used to identify the mainphysiological races ofPlasmodiophora brassicae collected from some regions in Huangshan city, Anhui province.The resistance of 30 oilseed cultivars to clubroot was evaluated under field conditions in Huangshan. The resultindicated that the main races of clubroot disease in Huangshan were No.4 and No.9 physiological races. Cultivars＇Quanyinyou 5＇ and ＇Deyouzaol＇ are resistant to clubroot. These cultivars are recommended as predominant cul-tivars and breeding materials in clubroot infected regions.
