| 摘 要： | 对不同来源陆地棉２０个品种（系）在新疆特定生态条件下的１３个性状进行了主成分分析。结果表明：纤维品质因子、产量因子、单铃重因子、衣分因子、第一果枝高度因子对变异的累计贡献率达８４．３％，对２０份材料的聚类分析结果表明：晋棉１２号、中棉所２５号、晋棉１９号和中棉所１９号等可划发为第一类；布哈拉６号、吉尔吉斯３号和新陆中５号等可划分为第二类；中棉所１７号、新陆中２号和爱ＳＪ－５等可划分为第三类。

| Abstract: | Principal component analysis were performed for13 characters among 20 upland cotton varieties with different sources.The result showed that the cumulative contribution of former 5 factors come up to 84.3%.The former 5 factors are quality factor and yield factor and single boll weight factor and ginturnout factor and the height of first fruit branch.Cluster analysis was used to analyse too.20 varieties were grouped into three clusters.Jinmianl2 and Zm25 and Jinmianl9 and Zm19 etc are first cluster.Buha1a3 and Jirjis3 and xlz5 etc are second cluster.Zm17 and Xlz2 and Acalasfj-5 etc are third cluster. |
