小豆产量相关性状的基因型与环境互作效应及稳定性分析
Analysis of genotype×environment interaction and stability of yield-related traits in adzuki bean(Vigna angularis)
摘要
Abstract
To evaluate the yield potential,adaptability,and stability of major cultivated adzuki bean varieties in China—and to provide guidance for regional application and breeding strategies—this study conducted multi-location trials involving 15 adzuki bean genotypes across eight representative ecological testing sites in major production areas during 2022 and 2023.A combination of joint variance analysis,correlation analysis,the additive main effects and multiplicative interaction(AMMI)model,and geno-type-by-environment interaction(GGE)biplot analysis was used to comprehensively assess yield and related agronomic traits.The results from the combined ANOVA showed that environmental factors were the primary drivers of variation in all traits ex-cept 100-seed weight,which was mainly influenced by genotype.The genotype×environment(G×E)interaction had a highly significant effect on yield and the number of main stem branches.Correlation analysis indicated that yield was strongly positively correlated with the number of pods per plant,identifying it as the core factor determining yield.AMMI and GGE analyses pre-cisely revealed complex G×E interaction patterns,clarifying the specific adaptation zones and stability differences among geno-types.Comprehensive evaluation showed that genotype G5 exhibited high yield potential and was closest to an ideal genotype;genotypes such as G8 possessed both high yield and stable performance.Environmental assessment indicated that the Yulin(E5)testing site,owing to its excellent representativeness and discrimination ability,was identified as an ideal testing environment.Overall,the study confirms that environmental effects play a dominant role in shaping yield-related traits in adzuki bean,and that genotype×environment interaction must be fully considered in variety selection and promotion,and the number of pods per plant can serve as a core selection index for high-yield breeding.This study provides key data support and scientific guidance for the optimization of adzuki bean breeding strategies and the precise promotion of varieties in China.关键词
