摘　　要：对32份大豆种质资源的9个农艺性状及产量进行了综合分析。结果表明,参试种质资源有效分枝数变异系数最高(30.37%),生育日数最低(2.19%);主成分分析获得了3个主成分因子,累计贡献率达到63.14%;聚类分析将32份大豆种质资源划分为4个类群,其中第IV类具有较高的增产潜力,可作为夏大豆新品种选育的重要种质资源。Using 32 soybean germplasm resources as materials,nine agronomic traits and yield were comprehensively analyzed.The re⁃sults showed that the highest coefficient of variation was found in the effective branch(30.37%),and the lowest was the number of growing days(2.19%).Three principal component factors were obtained by principal component analysis,and the cumulative contri⁃bution rate reached 63.14%.The 32 soybean resources were divided into four groups by cluster analysis,among which class IV had higher yield-increasing potential and could be used as important germplasm resources for breeding new summer soybean varieties.
