绿豆种质资源农艺性状和SSR分子标记的遗传多样性分析
Analysis of Genetic Diversity in Agronomic Traits and SSR Molecular Markers of Mung Bean Germplasm Resources
摘要
Abstract
Research on mung bean(Vigna radiata)trails significantly lags behind that of major crops,resulting in relatively slow progress in variety development.To investigate the genetic diversity of mung bean,this study analyzed 91 germplasm accessions from different regions using a multi-faceted approach that combined field-based morphological markers and SSR molecular markers.Morphological traits exhibited the highest level of genetic diversity,with compound leaf shape and pod width showing the largest coef-ficients of variation(CVs).The mean genetic diversity indices for qualitative and quantitative traits were 0.599 3 and 1.951 6,re-spectively,with corresponding mean CVs of 0.326 9 and 0.245 5.UPGMA clustering based on phenotypic traits categorized the ac-cessions into five clusters,with Clusters I and III showing superior overall performance.Principal component analysis(PCA)of the germplasm accessions identified eleven principal components(PCs)with eigenvalues greater than 1,collectively explaining 70.752%of the total variance.Among the 91 mung bean accessions,CL0009 exhibited the best overall performance.Additionally,six pairs of SSR primers detected 23 polymorphic bands,classifying the mung bean germplasm accessions into six clusters.These re-sults provided a theoretical basis for mung bean variety breeding and improvement.关键词
