长江流域棉区以枯萎病发生危害为主;黄河流域棉区枯、黄萎病多混合发生为害.近年来,枯萎病为主的混生区随着抗枯萎品种的推广和综合措施防治,病情已显著压低,但黄萎病又有所抬头。因此,在继续搞好抗枯萎育种的同时,加强对棉花品种资源抗黄萎鉴定和培育兼抗枯,黄萎新品种显得十分重要。为了“互通情报”,现将1974—1978年在苗庄大队科研基点进行的棉花品种资源抗黄萎病田间鉴定结果加以整理,提供有关育种和生产单位参考。
In the cotton area of the Yangtze River Basin, the occurrence of the wilt disease is the main cause of the disease. In the Yellow River Basin, the mixed occurrence of withered and Verticillium wilt occurred. In recent years, the blight-dominated mixed area has been treated with the promotion and comprehensive measures to combat the wilt. Significantly lower, but Verticillium wilt again. Therefore, while continuing to improve the resistance to wilt breeding, it is very important to strengthen the identification of anti-wilt and cultivate new varieties of resistance to drought and wilt of cotton varieties. In order to “exchange information”, the identification results of cotton variety resources resistant to verticillium wilt in 1974 and 1978 conducted at the scientific research base of Miaozhuang Brigade were sorted out to provide references for breeding and production units.
