摘　　要：为筛选优异外源小麦种质材料,分析了94份引进小麦种质的有效穗数、穗粒数、千粒重等7个主要农艺性状的变异情况及它们间的相关性,并以7个主要农艺性状为指标,对94份小麦种质进行了聚类分析。结果表明,除了容重外,94份小麦材料的其他6个主要农艺性状均表现出较大的变异性,以不孕小穗数的变异系数(62.07%)最大;有效穗数、株高与产量的相关性达到极显著水平,有效穗数与千粒重极显著负相关;通过聚类分析,将供试材料分为9个类群,其中第Ⅱ类群的g-1020、g-1043、09A452等6份种质的产量三要素极为协调,产量水平与不孕小穗数也表现较好,可以用作配置杂交组合的亲本。In order to screen parental materials with excellent genes and utilize them in wheat breeding programs, seven major agronomic traits, such as effective ears, grain number per ear, and thousand ker- nel weight ect. of 94 foreign wheat germplasms were investigated and the dates were analyzed by clus- ter analysis and correlation analysis. The results showed that except for bulk density, all the other six traits showed a great degree of variation, while the sterile spikelet showed the greatest variance coeffi- cient （62.07%）. Effective ears and plant height showed the extremely significant positive correlation with yield while effective ears was extremely significant negative correlation with thousand kernel weight. These materials can be divided into nine groups through cluster analysis. The group II with six wheat varieties including g-1020,g-1043 and 09A452 presented high yield and fewer sterility spike- let,and the yield components of which act more synergistically. Therefore varieties in the group II can be used as breeding parents.
