摘要
[目的]为长江流域农业生产提供优良的短季棉品系资源.[方法]以黄河流域、西北内陆和长江流域等地区短季棉种质资源为基础,通过杂交、回交等常规育种手段,从后代筛选出适合长江流域种植的短季棉新品系.[结果]新品系A3(从皖Z0912×中棉所50后代选育)在产量、抗性、纤维品质、霜前花率等综合性状方面具备较强的竞争力.[结论]短季棉可有效缓解粮棉争地矛盾、策应农业供给侧结构性改革,应大力推广发展.
Abstract
[Objective]To provide elite lines of short-season cotton for agricultural production in the Yangtze River Basin.[Method] Short-season cotton germplasm from the Yellow River Basin, the Northwest Inland and the Yangtze River Basin were performed through hybridization, backcross breeding.Ultimately,the short-season cotton lines which were suitable for the Yangtze River Basin from the offspring were screened.[Result]The line of A3 (Anhui Z0912×CCRI 50 progeny selection) has more competitive power in comprehensive traits such as yield, resistance, fiber quality and the boll ratio before frost.[Conclusion]Short-season cotton should be vigorously promoted because it can effectively alleviate the contradiction between grain and cotton and coordinate the agricultural supply side structural reform.
