新疆新陆早系列品种系谱分析与育种方向

通过对新疆新陆早系列品种系谱分析认为,近10年育成品种,产量不断提高,熟性有变晚趋势,抗病性逐步增强,抗枯萎病已基本解决,抗黄萎病有待进一步提高,品质得到改良,但品种类型单一,不能满足我区棉花产业化发展长远要求.因此,需要育种工作者通过拓宽遗传资源、创新种质,结合先进育种方法,并加强抗逆性筛选力度等来选育适合不同要求的棉花新品种.

Analysis on Line Family of the Early Maturing Upland Cotton Varieties of Xinjiang and the Discussion of Breeding Direction

By analysis of line family of Xinjiang the early upland cotton for more than 10 years,the result indicated the yield of varieties increased continuously, the ripe traits became late, and the disease resistance (Fusarium wilt and Verticillium wilt)raised gradually. The resistance to Fusarium wilt has been basically resolved, the resistance to Verticuillium wilt need further betterment, and cotton qualities improved gradually. But kind of varieties was single, and it didn't satisfy long-term demand of our region cotton industrialization development. Therefore, breeding researcher bred kinds of new cotton variety to suit for requirements by means of widening the heredity resources, innovating germplasm, using advanced breeding method, and strengthening resistant selection.
