Collection and Evaluation of Mung Bean Germplasm Resources in Hunan Province
摘要
Abstract
The genetic diversity analysis was conducted on 176 mung bean germplasm resources collected across Hunan province from 2015 to 2022.Our findings revealed a broad geographical distribution of these accessions across the province,exhibiting a wide altitudinal gradient.The genetic diversity index for qualitative traits was relatively low,whereas quantitative traits was detected with significantly higher diversity with greater coefficients of variation.Cluster analysis segregated the 176 germplasm resources into six distinct groups,each exhibiting unique phenotypic characteristics:group Ⅱ,characterized by multiple branches and high yield,groupⅢ by dwarf architecture,and group VI by tall stature,elongated pods,and large seed size.Principal component analysis of ten quantitative traits yielded five principal components with eigenvalues exceeding 1,accounting for a cumulative contribution rate of 79.959%.Through comprehensive evaluation,the accessions received scores ranging from 0.138 to 0.588.Seven superior germplasm resources with scores exceeding 0.5 were identified,including two long-pod,two high-yield,two tall-stature,and one large-seed accession.This study provides a multidimensional analysis of mung bean germplasm resources in Hunan province,offering valuable insights for future germplasm innovation and new variety breeding.关键词
