黄淮海11个夏大豆品种(系)产量稳定性和适应性分析OA北大核心CSTPCD

In order to study the stability and adaptability of soybean varieties(lines)and screen excellent soybean varieties(lines),multiple factor analysis of variance and GGE biplot were used to analysis on the region experimental data of National Huang-Huai-Hai(south)summer soybean from 2020 to 2021.The results showed that all factors and interaction effects had extremely significant effects on soybean yield(P＜0.01)except for the year factor.Location(55.31％)had a greater contribution rate to soybean yield,while contribution rates of variety(5.97％)and year(0.02％)to soybean yield were the smallest.Multiple comparative analyzes showed that Jining with the highest average yield was 33.63％higher than Fuyang with the lowest average yield,and the differences were significant(P＜0.05).Handou 13 with the highest average yield among the 1-1 tested varieties which increased by 10.93％and 9.91％respectively compared to the control Zhonghuang 13(CKA)and Zhonghuang 13(CKB),and the differences were significant.The GGE biplot analysis results showed that Guanyun and Xuzhou in Jiangsu,Linyi and Jining in Shandong had high similarity,and the location might be repeated.Zhoukou had the strongest discrimination and representativeness of the varieties tested,which was an ideal location.The 12 locations were divided into two groups,with Xu 9416-8 had the highest yield in the first group and Liudou108 had the highest yield in the second group.The analysis results of high yield and stability showed that Handu 13,Shengyu 6,and Nannong 60 had high yield and stability.In this study,soybean varieties with high stability and adaptability were selected,which also provided reference for the promotion and application of excellent germplasm resources.
