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。

Abstract: Using 32 soybean germplasm resources as materials,nine agronomic traits and yield were comprehensively analyzed. The results 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 contribution 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.

Key words: summer soybean, agronomic traits, yield, principal component analysis, cluster analysis
