An investigation was undertaken to evaluate thirty five genotypes of green gram from F2 generation along with ten parents and one local check with a view to study the magnitude of genetic variability, heritability and genetic advance for yield and yield contributing traits. A wide range of variation was observed for all the characters under study. Highest and lowest coefficient of variation was noticed in the traits yield per plant and days to maturity respectively. The traits days to initiation of flowering, days to fifty per cent flowering, days to maturity and hundred seed weight exhibited close differences between PCV and GCV. In general phenotypic coefficient of variation was higher than the genotypic coefficient of variation for all the characters under study which indicates that the expression of genotype is affected by environmental factor. The traits viz; grain yield per plant, plant height, number of pods per plant and number of branches per plant recorded low to moderate magnitude of PCV and GCV along with high to moderate heritability. Plant height recorded high heritability coupled with high genetic advance as per cent mean which indicated that this character is governed by additive genes and selection will be rewarding for its improvement while number of branches per plant, number of pods per plant and grain yield per plant exhibited moderate to high heritability coupled with moderate genetic advance per cent of mean.
