Comprehensive Evaluation of Soybean Germplasm Resources in Western Songnen Plain of Heilongjiang Province
摘要
Abstract
In order to fully explore and utilize soybean germplasm resources in Heilongjiang Province,clarify the correlation between traits,and improve the utilization rate of germplasm resources in the western Songnen Plain of Heilongjiang Province,this study analyzed multiple phenotypic traits of 266 soybean germplasm resources in the western part of the Songnen Plain in Heilongjiang Province using methods such as diversity analysis,correlation analysis,cluster analysis,and principal component analysis.The results showed that the coefficient of variation ranged from 4.55%to 144.22%among the tested germplasm resources,with the highest coefficient of variation for effective branchesnumber and the lowest coefficient of variation for protein.The cumulative contribution rate of the five principal components(eigenvalues greater than 1)reached 79.078%,which included factors such as pods number per plant,seeds number per plant,seeds weight per plant,growth period,and plant height.Through cluster analysis,they were divided into five categories.Among them,the second category was mainly characterized by short growth period,low bottom pod height,dense pod formation,good quality,and comprehensive traits good.Through the analysis of the collected local soybean germplasm resources,this study has certain reference significance for the effective utilization of the phenotypic traits of soybean germplasm resources in breeding in the western Songnen Plain of Heilongjiang Province.At the same time,it provides reference for the cultivation of new soybean varieties and the exploration of germplasm resources in Heilongjiang Province.关键词
