棉花黄萎病菌(Verticillium dahliae Kleb.)的10个菌系接种在属于三大棉种(海岛棉,陆地棉,中棉)的9个鉴别寄主上,按致病力强弱,初步分为3个生理型,印生理型1号——致病力最强的陕西省泾阳县菌系,对3大棉种都严重感染;生理型2号——致病力最弱的新疆和田、车排子菌系,对所有鉴别寄主感染很轻;生理型3号——致病力介于1、2号之间,其它6省8县的菌系属于此类型。
Ten bacterial strains of Verticillium dahliae Kleb. Were inoculated on 9 differential hosts belonging to the three major cotton species (sea island cotton, upland cotton and cotton plant), and were initially divided into 3 Physiological type, Physiological type 1 - the strongest pathogenic strains of Jingyang County in Shaanxi Province, the three major cotton species are severely infected; Physiological 2 - the weakest Xinjiang Wada, car row Subsystem, all of the identification of host infection is very light; Physiological No. 3 - Pathogenicity between No. 1 and No. 2, the other 6 provinces and 8 counties of the strains belong to this type.
