摘　　要：通过随机区组设计,对9个组合材料的F2代进行农艺性状、产量和品质等性状测定,其结果是:抗棉铃虫性能最好的是制1(F2代材料代号,后同)、制92、制97、制99、制100,均达到高抗级;制3、制99、制92、制97、制100为高产组合,子棉产量达到4 072.8～4 398.5 kg/hm2;皮棉产量以制3、制97和制99较高;纤维品质较好的是制3、制92、制93、制97;筛选出强优势组合是制3、制92、制97。This test adopted randomised block design,determined the expression of growing characters,yield and quality about 9 combinations F2 generation.The results indicated that ： Zhi 1 was the best on anti-bollwormother,Zhi92,Zhi97,Zhi99 and Zhi100 were all the highest,the high-yielding combinations were Zhi3, Zhi99,Zhi92,Zhi97and Zhi100,the yield was 4072.8 ～ 4398.5 kg/ hm2;the lint cotton yield of Zhi3,Zhi97and Zhi 99 were higher;The better fibrequality were Zhi3,Zhi92,Zhi93and Zhi97;screened out the strong heterosis combinations ：Zhi3,Zhi92 and Zhi97.
