Abstract:
Study the extent of stability parameters in vegetable cowpea for twelve traits and 24 hybrids along with 11 parents were evaluated with three replications in randomized block design under four environments. Phenotypic stability by Eberhart and Russel model indicated highly significant genotype × environment for majority of traits, emphasizing the different reply of genotypes to varied environments. This information is crucial for breeders to select cultivars that exhibit stability across diverse environmental conditions. Linear and non-linear elements in gene × environment relation was highlighted through the analysis of variance of phenotypic stability. None of the parents or hybrids was found to be average stable for entire characters across environments. Among the identified stable hybrids for green pod yield per plant (g), GP 30 × Pusa falguni studied as the best-performing hybrid.
