棉花枯萎病是危害棉花最严重的病害之一。近几年来,由于采用以种植抗病品种为主的综合防治措施,有效地控制了危害。但目前推广的抗病品种在丰产性和品质方面还不能满足生产的需要,因此,品种既抗病又高产成为抗病育种急待解决的问题。我们从1972年开始,经六年的努力。选育出高抗枯萎病、高产、品质好的新品种“86—1号”。根据1976—1977年两年全国抗病品种区域试验结果,被推荐为长江流域病区和黄河流域高水肥枯萎病区的推广品种。在无病点试验表明,“86—1号”与当地推广的感病丰产品种比较,也有所增产。
Cotton Fusarium wilt is one of the most serious diseases that endanger cotton. In recent years, due to the adoption of a comprehensive prevention and control measures to plant resistant varieties, effectively control the hazards. However, the current popularized disease-resistant varieties can not meet the needs of production in terms of high yield and quality. Therefore, the varieties are both disease-resistant and high-yielding, which have become urgent problems to be solved in disease resistance breeding. We started in 1972, after six years of hard work. Breeding high resistance to blight, high yield, good quality new variety “86-1 number.” According to the regional test results of the national disease-resistant varieties in two years from 1976 to 1977, it is recommended to promote the varieties of high-water and fat-fusarium wilt in the Yangtze River Basin and the Yellow River Basin. Disease-free trials showed that “86-1” was also increased compared with the locally-introduced high-yielding susceptible varieties.
