Comprehensive Evaluation of Zhenglü 20 in GGE Biplot Analysis of Varieties in Regional Trials
A correlation analysis was conducted on the agronomic and yield traits of ten new mung bean vari-eties tested in multiple sites in Henan Province for two consecutive years,and their correlation relationships were explored.GGE Biplot was used to analyze the tested varieties in the identification of new mung bean varieties in Henan Province from 2019 to 2020.The high yield,stable yield,adaptability of the tested varieties,representa-tiveness,discrimination,and differentiation ability of each pilot experiment were comprehensively evaluated.The results indicated that the variation coefficients of plant height,branch number of the main stem,and pod number per plant were higher.The pod number per plant was positively correlated with the branch number and yield of the main stems,and the node number of the main stems was positively correlated with plant height.The four pilot areas can be divided into two ecological zones,as effectively reflected in the Biplot.Pilot in Anyang has a strong identification ability for varieties,and the'Zhenglü 20'has good yield and stability,with good overall perform-ance and extension value.
