Abstract
The present study was conducted to examine the genetic basis of yield and its related components, enabling selection based on heritability and genetic gain. The experiment involved the evaluation of fourteen accessions of green gram in Kharif season of year 2024 in a randomized complete block design. Data were collected from ten important yield related characters and analysed statistically. ANOVA revealed significant variation in the genetic material used in the study. Among the studied genotypes, CO 7, CO 4, CO 8, and CO 6 were identified as superior for seed yield based on their mean performance.The phenotypic coefficient of variation exceeded the genotypic coefficient of variation, indicating that the observed variation between the two is primarily due to the genotypes, with minimal environmental influence. Notably, single trait, number of pods per plant exhibited both high heritability and high genetic advance.
