Genetic Diversity Analysis of Agronomic Traits in Radish Germplasm
摘要
Abstract
Utilizing 315 radish(Raphanus sativus L.)germplasm resources as experimental materials,19 agronomic traits were systematically characterized,and their genetic diversity was comprehensively analyzed.The results demonstrated that the coefficient of variation(CV)for these traits ranged from 7.91%to 91.05%,with the highest CV observed in the skin color of the subterranean part of the fleshy root and the lowest in the bitterness intensity of the fleshy root.The genetic diversity index varied between 0.04 and 2.07,with a mean value of 1.41.Specifically,quantitative traits exhibited diversity indices spanning 1.94-2.07,whereas qualitative traits ranged from 0.04 to 1.54.Significant or highly significant correlations were identified among 91 pairwise combinations of traits.And the first eight principal components cumulatively contributed 77.40%of the total variance,encapsulating the majority of genetic information.Cluster analysis classified the 315 radish accessions into three major groups and four subgroups.These findings provide critical insights for the conservation,utilization,and genetic breeding of radish germplasm resources.关键词
