选育和推广种植抗病品种控制棉花枯、黄萎病为害是最经济有效的措施。而感病品种,则减产30—50%,严重的造成绝收。当前,棉花黄萎病蔓延迅速。因此,尽快选育出抗黄萎病和兼抗(耐)枯、黄萎病优质丰产的新品种是当务之急。选育棉花抗病品种必须建立一个发病重而又均匀的病圃,只有在这样诱发侵染的环境下,才能对棉花品种(系)种质资源和杂交后代等进行抗性鉴定。同时,还可在病圃中连续选择,以提高棉花抗性转育和现有材料的抗病性。
It is the most economical and effective measure to breed and popularize the disease-resistant varieties to control the damage of cotton withered and Verticillium wilt. The susceptible varieties, then cut 30-50%, resulting in serious failure. At present, the rapid spread of cotton verticillium wilt. Therefore, it is imperative to bred new varieties of Verticillium dahliae resistant and resistant (withered) and Verticillium wilt with high quality and high yield as soon as possible. Breeding cotton resistant varieties must establish a heavy and uniform disease nursery, and only in such an environment of induced infection, cotton varieties (lines) germplasm resources and hybrid progenies, such as resistance identification. At the same time, continuous selection can also be made in the nursery to improve the resistance of cotton to transformation and existing materials.
