Abstract
The Peanut (Arachis hypogaea L.) is a self-pollinated and allotetraploid crop. Eight advanced breeding lines which are derived from three crosses viz., TMV-2 × ICGV- 91114, TMV-2 × TG-69 and TMV-2 × ICGV-00350 along with two checks viz., TMV-2 and K-6 following RCBD with three replications were sown at NSP, GKVK, Bengaluru, OFRS Mandya and ARS, Balajigapade during Kharif 2021 and Rabi 2021. Based on GGE biplot for ranking of genotypes during Kharif 2021, ABLs viz., T82 and T72 were found to be adaptable whereas during Rabi 2021, ABL T89 was found to be adaptable for kernel yield plant-1. “Which won where pattern” of GGE biplot showed that during Kharif 2021, ABLs T72 and T82 were winning genotype in GKVK, ABLs T77, T65 and
T61 were winning genotypes in Mandya and ABL T89 was found to be winning genotype in Balajigapade for kernel yield plant-1. During Rabi 2021, ABL T72 was found to be winning genotype in GKVK, ABLs T65 and T79 were found to be winning genotype in Mandya and ABL T89 was found to be winning genotype in Balajigapade for kernel yield plant-1. Based on ASV and SI, for kernel yield plant-1, during Kharif 2021 ABLs T65, T77, T81 and T82 were found to be adaptable whereas during Rabi 2021
ABLs T77, T81, T82 and T65 were found to be stable. ABLs T65, T77, T81 and T82 were found to be stable across the season. The stable lines identified can be used as a parents in developing segregating population.
