Diversity Analysis and Comprehensive Evaluation of Phenotypic Traits in 72 Phaseolus vulgaris Resources
In order to fully utilize high-quality common kidney bean resources,72 kidney bean resources from 3 countries were used as research materials,and membership function,Shannon-Wiener's diversity index,principal component analysis and cluster analysis were used to evaluate 10 phenotypic traits.The results showed that the coefficient of variation of the 10 traits ranged from 13.9%to 52.1%,and the phenotypic diversity index ranged from 1.354 to 2.209.The close degree between traits and plot yield was the yield per plant＞plant height＞pod width＞pod number per plant＞seed number per pod＞pod length＞pod number per node＞branch number per plant＞100-seed weight.The UMAP Cluster analysis grouped 72 kidney bean resources into three groups,with Brazil relatively far from Mexico and Guatemala,and 72 kidney bean resources were clustered into three groups,group Ⅰ includes 25 kidney bean resources,including 10 from Brazil,10 from Mexico and 5 from Guatemala,and Group Ⅱ includes 25 kidney bean resources,including 4 from Brazil,14 from Mexico and 7 from Guatemala.Group Ⅲ includes 22 resources,including 3 resources in Brazil,14 resources in Mexico and 5 resources in Guatemala.Ten excellent resources(YJ010459,YJ00992-A,YJ009764,YJ010450,YJ010490,YJ010092-A,YJ010270,YJ009749,YJ009789 and YJ010012)were selected by principal component analysis and membership function evaluation.
