摘要

在旱作条件下,对23个基因型绿豆在2016年(E1)、2017年(E2)和2018年(E3)连续3年不同环境下的稳定性进行了评价。Pusa Vishal基因型的回归系数基本一致,与回归系数偏差不显著,对环境的适应性较好或较差。基因型EC520016成熟早,适应性广。环境指标表明,E2和E3环境对产量和大部分产量属性性状最有利,而单独E3环境对种子产量/株和种子/荚数最重要。基于AMMI模型,Pusa Vishal、PD139、IPM2-3、IPM2057和PML2-14在E3表现出较高的IPCA评分和较高的种群平均值。AMMI2分析表明,ML2056和K851在E3中具有高IPCA1水平,而IPM99-125、BM63和PM2-14在相同环境中具有高IPCA2水平。非常靠近中心点的基因型受gx E相互作用的影响最小,而远离中心点的基因型受gx E相互作用的影响更大,因此不稳定。所鉴定的基因型可用于靶环境的辐射维尼亚改良计划。

Study on genotype x environment interactions and AMMI analysis for agronomic traits in mungbean (Vigna radiata L. Wilczek.) under rainfed conditions.
In the present study, 23 genotypes of mungbean were evaluated for stability performance under different environments continuously for three years during kharif 2016 (E1), 2017 (E2) and 2018 (E3) under rainfed conditions. Genotype Pusa Vishal exhibited regression coefficient equal to unity with non-significant deviation from regression coefficient and hence showed wider adaptability under poor or good environments. Genotype EC520016 showed earliness in maturity with wider adaptability. Environmental indices indicated that environment E2 and E3 were most favourable for yield and majority of yield attributing traits, whereas E3 alone was important for seed yield/plant and number of seeds/ pod. Based on AMMI models, Pusa Vishal, PD139, IPM2-3, IPM2057 and PML2-14 showed higher IPCA scores coupled with high population mean in E3. AMMI2 analysis indicated ML2056, and K851 with high IPCA1 in E3 whereas IPM99-125, BM63 and PM2-14 with high IPCA2 in the same environment. Genotypes which positioned very close to centre point and are least effected by G x E interactions while those presented away from the point of centre are more affected by G x E interactions and hence not stable. Identified genotypes may be utilized in improvement programme of Vigna radiata for targeted environments.
