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。
Cruciferous crop clubroot disease occurs more and more in the rapeseed planting area of Huangshan City, Anhui Province, and has become an important factor that limits the yield and quality of rapeseed. In order to identify the physiological races of R. solani and the rapeseed cultivars in Huangshan, Anhui province, Williams method was used to identify P. rapa in some areas of Huangshan City, Anhui Province. Resistance to 30 rape cultivars was studied in areas with severe clubroot disease. The results showed that at present, the pathogen of P. euphratica in Huangshan Mountain of Anhui Province is physiological race 4 and 9. Tsuen silver oil on the 5th, German oil early on the 1st and other varieties of resistant varieties. These varieties can be used as the local species of clubroot disease wilderness varieties and breeding materials.
