Comprehensive evaluation of soybean germplasm resources based on entropy weight TOPSIS method
9 soybean germplasm resources were selected,including JD001,JD002,and JD003,as materials,and 8 agronomic traits such as plant height,bottom pod height and main stem node number were evaluated by entropy weight TOPSIS method,and then cluster analysis was carried out in order to provide theoretical references for the breeding of new soybean varieties.The results showed that among various agronomic traits,the ones with higher coefficients of variation were effective branch number per plant(64.79%),bottom pod height(31.44%),and effective pod number per plant(28.77%),indicating that these 3 traits have rich genetic improvement potential and can be applied to soybean variety breeding and identification.Through entropy weight TOPSIS method and cluster analysis,9 soybean varieties were divided into three types,one was JD006(good type),the second category were JD001,JD004,JD005 and JD009(medium type),the third category were JD002,JD003,JD007 and JD008(general type).Among them,the soybean variety JD006 was suitable for use as a high-quality parent.
