系统选育虽然存在着被动性和局限性,但只要方法正确,也能相对的克服这些缺点,并在较短时间内,提供优良的新品种,故仍不失为棉花育种的一个主要途径.我们根据塔里木河流域历年棉花系统选育的经验,对本流域选育目标、单株选择技术有如下的认识,现提请育种工作者指正. Although systematic breeding has its passivity and limitation, as long as the methods are correct, it can relatively overcome these shortcomings and provide excellent new varieties in a relatively short time, so it is still one of the main ways for cotton breeding. The experience of cotton system selection and breeding in the Tarim River Basin over the years has the following recognition on breeding target and single plant selection techniques in this drainage basin and hereby invites breeders to correct it.
