棉花枯萎病和黄萎病是当前严重危害棉花生长的两种病害,是我国的植物检疫对象。为了落实毛主席关于“必须把棉花抓紧”的伟大指示,全国各地广大贫下中农和科技人员积极开展了对棉花枯、黄萎病的综合防治,取得了很大效果,现将国内研究概况介绍如下:一、抗枯、黄萎病品种选育及应用陕西、四川、江苏、山西是国内发病最早的地区。解放后,四川、江苏、辽宁等省先后选育出抗枯萎病的棉花品种有52—128、57—50、南通二号,抗黄萎品种辽棉二号等,曾在重病区生产中发挥一定作用。但随着病区的扩大,这些抗病品种在数量和质量上均不能满足
Cotton Fusarium wilt and Verticillium wilt are the two kinds of diseases that seriously endanger the growth of cotton and are the target of plant quarantine in our country. In order to implement Chairman Mao’s great instructions on “the cotton must be grasped tightly,” the vast number of poor and middle-level peasants and scientific and technological personnel in various parts of the country have taken an active part in the comprehensive prevention and control of cotton blight and verticillium wilt and have achieved great results.

After the liberation, Sichuan, Jiangsu, Liaoning and other provinces have bred the resistance to blight cotton varieties 52-128,57-50, Nantong two, anti-yellowing varieties such as Liaomian two, had played in the production of serious ward Certain effect. However, with the expansion of the ward, these resistant varieties can not be met in quantity and quality
