| 摘 要： | 产量因素性状与产量的偏相关及通径分析结果一致表明,株铃、铃重与衣分为三大产量因素,以株铃对产量的贡献最大,铃重次之,衣分居三。纤维品质性状的偏相关及通径分析表明,选择整齐度高、比强度大、麦克隆值低的性状,不仅可提高纺纱均匀性指数,且对改善子棉产量亦有一定的促进作用。典型相关分析结果显示,增加株铃,有利于提高皮棉产量和增进纤维品质,但株铃过多,晚秋桃所占比例大,将对衣分、衣指、麦克隆值产生负效应,因此,应注意优化成铃时间与部位,力争多结优质铃。

| Abstract: | Partial relation and path analysis result of yield traits and yield shows that bolls per plant, boll weight and lint percentage are the three big yield elements and among which bolls per plant contribute the most to yield ,then boll weight, and then lint percentage. Partial relation and path analysis of fiber quality traits indicates that the selection of traits with high uniformity of cotton fiber, great fiber strength,low micronaire value could not only increase the spinning consistence index but also promote the cotton yield. The result of canonical relative analysis shows that increasing bolls per plant would be benefit to improve cotton yield and fiber quality, but with more bolls per plant and high proportion of late autumn bolls, side effect could be caused on lint percentage,lint index and mieronaire value, so attention should be paid to the boll time and position in order to achieve good bolls. |
