研究了3个正常叶型材料与鸡脚叶型材料杂交得到的杂种2代结果表明,选用适当亲本组配的杂交组合,不仅F_1能获得高产,F_2也有一定利用价值,其中尤以鄂棉15×鸡-2最好。对几个农艺性状与产量的相关分析表明,在条裂叶型、正常叶型材料中,果枝数、果节数与皮棉产量达显著正相关,条裂叶型F_2的纤维长度高于正常叶型。以合理正常叶植株与条裂叶植株的比例和适当的栽培措施改善农艺性状,便能提高F_2的产量和纤维品质。 The results of hybrid 2 generations obtained from the crossing of three normal leaf materials with the chicken leaf type material showed that the F1 hybrids could not only be used for the high yield but also for the F_2, 15 × chicken -2 best. Correlation analysis of several agronomic traits and yield showed that there was a significant positive correlation between the number of fruit branches and the lint yield in stripped leaves and normal leaves. The length of fibers in stripped leaves was higher than that in normal leaves type. In order to improve the agronomic characters by the ratio of reasonable normal leaf and split leaf plant and appropriate cultivation measures, the yield and fiber quality of F_2 can be improved.
