The objective of this study was to determine drought tolerance, kernel (KY) and fodder yield and quality amongst diverse groundnut genotypes for direct production or breeding. Hundred genotypes were evaluated at ICRISAT, India during 2018–2019 and 2019–2020 under drought-stressed (DS) and nonstressed (NS) conditions. Data were collected on KY; oil content (OC); oil yield (OY); protein content; palmitic, stearic, oleic, and linoleic acid contents; haulm yield (HY); and fodder quality parameters such as the contents of dry matter, ash, nitrogen (NC), neutral detergent fiber (NDFDM), acid detergent fiber (ADFDM), acid detergent lignin (ADLDM), in vitro digestibility, and metabolizable energy. Data were subjected to parametric and nonparametric statistical analyses. Combined analysis of variance revealed significant (P < .05) genotype differences for all assessed traits. Genotype × water regime interaction effects were significant for KY, OC, ash, NC, NDFDM, and ADLDM. Kernel yield positively and significantly (P < .05) correlated with OY (r = .99), LAC (r = .13), ash (r = .32), and NDFDM (r = .54) under DS condition. Haulm yield was positively and significantly (P < .05) correlated with OC (r = .24), NDFDM (r = .19), ADFDM (r = .18), and ADLDM (r = .17) under DS condition. The study identified four genotypes with high kernel and haulm yields, and six genotypes with high oleic acid content. Further, 10 genotypes were selected with relatively better drought tolerance. The selected genotypes are recommended for further breeding and variety release adapted to drought conditions.

干旱条件下花生 (Arachis hypogaea L.) 基因型的遗传多样性评估对籽粒产量、油料和饲料的数量和质量

本研究的目的是确定用于直接生产或育种的不同花生基因型的耐旱性、籽粒 (KY) 和饲料产量和质量。2018-2019 年和 2019-2020 年，在干旱胁迫 (DS) 和非胁迫 (NS) 条件下，在印度 ICRISAT 评估了数百种基因型。数据是在 KY 上收集的；含油量（OC）；油产量（OY）；蛋白质含量; 棕榈酸、硬脂酸、油酸和亚油酸含量；稻草产量（HY）；和饲料质量参数，如干物质、灰分、氮 (NC)、中性洗涤纤维 (NDFDM)、酸性洗涤纤维 (ADFDM)、酸性洗涤木质素 (ADLDM)、体外消化率和代谢能的含量。数据进行参数和非参数统计分析。方差的组合分析显示显着（P < .05) 所有评估性状的基因型差异。KY、OC、灰分、NC、NDFDM 和 ADLDM 的基因型 × 水体相互作用效应显着。 在 DS 条件下 ，籽粒产量 与 OY ( r  = .99)、LAC ( r  = .13)、灰分 ( r = .32) 和 NDFDM ( r = .54)呈显着正相关( P < .05) 。稻草产率为正和显著（P  <0.05）与OC（相关- [R  = 0.24），NDFDM（[R  = 0.19），ADFDM（[R  = 0.18），和ADLDM（ř = .17) 在 DS 条件下。该研究确定了具有高籽粒和稻草产量的四种基因型，以及具有高油酸含量的六种基因型。进一步筛选出耐旱性较好的10个基因型。推荐选择的基因型用于适应干旱条件的进一步育种和品种发布。
