Abstract

Pigeonpea [Cajanus cajan (L.) Millspaugh] is an important pulse crop grown under Indian rainfed agriculture. Twenty eight pigeonpea genotypes were tested for stability and adaptability across ten rainfed locations in the States of Telangana and Karnataka, India using AMMI (additive main effects and multiplicative interaction) model and GGE (genotype and genotype by environment) biplot method. The grain yields were significantly affected by environment (56.8%) followed by genotype × environment interaction (27.6%) and genotype (18.6%) variances. Two mega environments were identified with several winning genotypes viz., ICPH 2740 (G15), TS 3R (G10), PRG 176 (G8) and ICPL 96058 (G22). E2 (Gulbarga, Karnataka), E3 (Bidar, Karnataka) and E6 (Vikarabad, Telangana) were the most discriminating environments. Genotypes, ICPH 2740, PRG 176 and TS 3R were the best cultivars in all the environments whereas PRG 158 (G9), ICPL 87119 (G12), ICPL 20098 (G19) and ICPL 96058 (G22) were suitable across a wide range of environments. Genotypes, ICPH 2740 and PRG 176 can be recommended on a large scale to the farmers with small holdings to enhance pigeonpea productivity and improve the food security

通过AMMI和GGE双图分析鉴定对雨养环境适应性较强的鸽豌豆基因型

鸽豆[Cajanus cajan (L.)]是印度雨养农业种植的一种重要的脉冲作物。利用AMMI(可加性主效应和乘法相互作用)模型和GGE(基因型和环境基因型)双图方法，对印度特伦甘纳邦和卡纳塔克邦10个旱地的28种鸽豌豆基因型的稳定性和适应性进行了测试。籽粒产量受环境的显著影响(56.8%)，其次是基因型-环境互作(27.6%)和基因型方差(18.6%)。在两个大型环境中鉴定出多个获胜基因型:icph2740 (G15)、TS 3R (G10)、prg176 (G8)和ICPL 96058 (G22)。E2(古尔巴加，卡纳塔克邦)，E3(比达尔，卡纳塔克邦)和E6(维卡拉巴德，泰伦加纳邦)是最具歧视性的环境。基因型中，icph2740、prg176和TS 3R是所有环境下的最佳栽培品种，而prg158 (G9)、ICPL 87119 (G12)、ICPL 20098 (G19)和ICPL 96058 (G22)是各种环境下的最佳栽培品种。基因型icph2740和prg176可大规模推荐给小农，以提高鸽豆产量，改善粮食安全
