摘　　要：以18个陆地棉杂交组合F_2代为研究对象,对其铃重、衣分、子棉、皮棉产量及纤维品质进行比较,筛选出能在生产上加以利用的杂交棉F_2代。结果表明:A11黄×Q2、A33×b19、A33×K61、K31×Q6组合综合性状表现好,株型分离小,皮棉产量分别比对照增产17.6%、13.6%、16.0%、19.6%,其纤维品质特别是绒长、马克隆值、比强度及纺纱均匀性指数表现极优,可以在洞庭湖棉区生产上加以利用。Taking 18 upland cotton hybrids F2 generation as analysis object, their boll weight, lint, seed cotton, lint yield and fiber quality were compared to screen F2 generation with excellent comprehensive characters. The results showed that： A 11 yellow×Q2, A33×b 19, A33×K61, K31×Q6 combination of good comprehensive traits, isolation of plant type, lint yield increased by 17.6%, 13.6%, 16.0%, 19.6%, respectively, compared with the control. In particular its quality cashmere fiber length, micronaire, strength and uniformity index spinning performance was excellent. So 4 combinations are fit to plant in Dongting Lake.
