摘要
用正常叶和鸡脚叶杂交的F_3为材料,考查了不同叶型的产量、纤维品质、早熟性、虫籽率和僵瓣率。试验结果表明:鸡脚叶对纤维品质没有不良的影响,与正常叶比较,红铃虫为害的虫籽率和僵瓣率分别低36%和29.2%,皮棉产量持平,霜前花率高12.2%,霜前皮棉产量高17%,但其缺点是后期表现出明显的早衰现象。
Yield, fiber quality, earliness, percentages of both the insect injuredseeds and stiff unginned cotton from different leaf shapes were investigatedusing F_3, the progeny from the cross or normal leaf × okra leaf. The resultsindicate that,as compared to the normal leaf,the okra leaf showed no negativeeffect on fiber quality but lowered percentages of both the pink bolloworminjured seeds and stiff unginned cotton. The lint yield of okra leaf was closeto that of normal leaf but the yield of the former before Frost Descent washigher and the former ripened earlier. The only disadvantage of okra leaf isits obviously early ageing at the later stage.
