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
