摘　　要：[目的]对新疆春小麦品种(系)农艺性状进行主成分分析和聚类分析。[方法]以30个新疆自育的春小麦品种(系)为参试品种(系),采用主成分分析和聚类分析法分析各品种(系)的农艺性状。[结果]生育期、最高总茎数、收获穗数和成穗率4个农艺性状是影响新疆春小麦产量的主要因子;在遗传距离8.37水平上将30份品种(系)分为4类。[结论]当春小麦品种(系)生育期较短,最高总茎数适中,收获穗数和成穗率较高时,较易获得高产。[ Objective ] Cluster analysis and principal component analysis were performed for the agronomic traits of spring wheat varieties （lines） in Xinjiang. [ Method] 30 spring wheat varieties（lines） were selected,the characters were analyzed by principal component analysis and cluster analysis. [Result] 4 agronomic traits （growth period,the highest total stem number, the number of spike and the rate of spike） were the main factors affecting the yield of spring wheat. 30 kinds of varieties （lines） were divided into 4 categories when the genetic distance was 8. 37. [ Conclusion] It9 s easy to obtain high yield when the growth period of spring wheat varieties （ l ines ） was shorter, the highest total stem number was moderate, the number of spike and the rate of spike were higher.
