Assessment of the genetic diversity of groundnut ( <i>Arachis hypogaea</i> L.) genotypes for kernel yield, oil and fodder quantity and quality under drought conditions

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