Abstract: The aim is to clarify the main types, the main agronomic traits characteristics and the diversity of types of common bean germplasm resource in Shanxi Province. 152 primary core collections of common bean in Shanxi were used as materials, the agronomic traits were identified in field, 24 traits of the 152 primary core collections were studied with cluster analysis, diversity analysis and principal component analysis. The results showed that the 152 primary core collections of common beans were divided into 5 groups. From the view of the diversity of clustering groups,I value based on diversity analysis of the semi-dwarfing+sprawl-purple stem and flower types as well as sprawl-seed stripes was the maximum, whileI value of erect type was the minimum. From the diversity of agronomic traits, the diversities of quality traits were lower than those of quantity traits, but the grain colors were more abundant. Through the principal component analysis, 23 agronomic traits were divided into 7 principal components, and the agronomic traits represented by the 7 principal components were clarified. Finally, the main types of common bean germplasm, diversity characteristics and the agronomic traits of the 7 principal components, which can supply some comprehensive trait indexes for germplasm assessment, were determined.
