摘要: 本研究通过对152份山西省普通菜豆初级核心种质进行农艺性状鉴定及农艺性状多样性分析,旨在明确山西省普通菜豆种质资源的主要类型,各类型及性状的主要农艺性状特征及多样性特点。通过在田间进行农艺性状鉴定,同时利用表型数据,采用聚类分析、多样性分析和主成分分析法,确定了山西省普通菜豆种质资源的主要类型,各类型和各性状的农艺性状特征和多样性特点以及24个表型性状所属的主成分。结果表明山西普通菜豆初级核心种质可划分为5种类型。从各分组多样性来看,半蔓+蔓生-紫茎紫花型和蔓生-籽粒斑纹型多样性指数I最高,而直立型资源多样性指数I最低,从各性状多样性来看,质量性状多样性总体低于数量性状,但粒色则表现出明显丰富的多样性。通过主成分分析,将普通菜豆23个农艺性状归属为7个主成分,初步明确了各主成分代表的农艺性状;通过上述研究,明确了山西普通菜豆主要类型、多样性特征和各主成分代表的主要农艺性状,可为资源鉴定评价提供综合性状指标。

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.
