Genetic Diversity and Comprehensive Evaluation in Hyacinth Bean(Lablab purpureus)Landraces from Zhejiang Province
摘要
Abstract
Based on 129 hyacinth bean landraces collected from Zhejiang province during"The Third National Census and Collection Campaign of Crop Germplasm Resources",this study systematically investigated their agronomic and quality traits.Combined with single nucleotide polymorphisms(SNPs)obtained from resequencing datasets,we conducted a comprehensive assessment of their genetic diversity of these landraces.The results revealed abundant genetic diversity in phenotypic traits among the hyacinth bean resources.Among the 13 qualitative traits analyzed,48 variant types were identified,with Shannon diversity index(H')ranging from 0.091 to 1.486.Pod shape exhibited the highest H',while young leaf color showed the lowest.Leaf color was predominantly green(98％),main stem color was mainly purple(49％),standard petal and wing petal colors were primarily light purple(69％)and purplish-red(69％),respectively.Pod color was mostly light green(35％),pod shape was mainly falcate(42％),seed shape was predominantly elliptical(57％),and seed color was mainly black(49％).For the 23 quantitative traits,the coefficients of variation(CV)ranged from 2.88％to 43.26％,with grain yield per plant having the highest CV,and water content the lowest.The Shannon diversity index(H')for quantitative traits ranged from 1.83 to 2.25,where soluble sugar content displayed the highest diversity and maturity duration the lowest.Principal component analysis(PCA)based on SNPs classified the 129 landraces into four clusters.Cluster Ⅰ had the lowest cellulose content(6.48％)and the highest crude protein content(20.34％);Cluster Ⅲ exhibited the highest water content(87.53％),soluble sugar content(21.88％),crude fat content(5.99％),and free amino acid content(7.98 mg/g);Cluster Ⅳ consisted of medicinal hyacinth beans with white flowers and white seeds.This study systematically elucidated the genetic diversity of lablab germplasm resources in Zhejiang province at the phenotypic,quality,and genotypic levels,providing a scientific basis for germplasm innovation and the breeding of new varieties.关键词
