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.
