| 摘 要： | 通过对百棉1号、百棉6号、豫棉668、海南1094个陆地棉品种(系)的30个不同部位棉铃的8个主要经济性状进行典型相关分析和因子分析,结果表明:提高单铃重(rux1=0.6980),会同步提高衣分((rux2=0.6556),间接增加整齐度(rux8=0.5399)、比强度(rux6=0.3197),但一定程度上对2.5%跨长(rux4=-0.3197)及麦克隆值(rux5=0.4799)带来不利的影响。

| Abstract: | In this paper,eight main economy characters which were distributed in the 30 different part boU on BM1、BM6、 YM668 and HN109 were analyzed by Canonical correlation analysis and factor analysis. The result indicated that with the raise of high boll weight (r_(ux1)=0.6980) , the lint percent (r_(ux2)=0.6556) would increase together, the uniformity(r_(ux8)=0.5399) and strength (r_(ux6)=0.3197) increased indirecdy, but it would lead to certain degree disadvantage influence to the length (r_(ux4)=-0.3197) and micronaire (r_(ux5)=0.4799) . |
