小豆种质资源产量性状的多环境评价与优异种质筛选
Multi-Environment Evaluation and Elite Germplasm Selection for Yield Traits in Adzuki Bean(Vigna angularis)
摘要
Abstract
The yield of adzuki bean(Vigna angular is)is a complex quantitative trait controlled by multiple genes,and is significantly influenced by genotype,environment,and genotype-by-environment interactions.To understand the genetic diversity and environmental effects on yield-related traits in adzuki bean germplasm,and to identify superior accessions,310 adzuki bean accessions from China and abroad were evaluated in field trials conducted over two years(2022-2023)at three ecologically diverse locations:Beijing,Qiqihar,and Nanning.Key yield-related traits,including plant height,growth period,pods per plant,seeds per pod,pod length,hundred-seed weight,and plot yield,were systematically investigated and analyzed.The results showed that all yield-related traits exhibited highly significant differences among different accessions and environments,and were significantly affected by genotype,environment,and genotype-by-environment interactions.Pods per plant,hundred-grain weight,plant height,number of primary branches,and seeds per pod were all significantly or highly significantly and positively correlated with plot yield,with pods per plant showing the strongest correlation coefficient.Path analysis revealed that pods per plant had the largest direct effect on plot yield.Cluster analysis based on yield-related traits grouped the 310 accessions into four clusters,with significant differences in yield traits among clusters.Comprehensive evaluation identified a set of accessions,such as Huaxiaodou(B0000282),and Hongxiaodou(B0004139)with desirable characteristics such as long pods,large seeds,high yield,and yield stability.This study reveals the genetic diversity and environmental adaptability of yield-related traits in adzuki bean,providing a theoretical basis and material foundation for the evaluation,selection,utilization,and breeding for high yield in adzuki bean.关键词
