Abstract The objective was to ascertain genetic variability, heritability and genetic advance of different traits for their utilization in crop improvement programs. Analysis of variance revealed highly significant differences for almost all the characters, except breadth of pods and number of primary branches which it was significant only at 5% level. This indicated the presence of much more variability among the genotypes used in the present study. But the number of seeds/pod showed non significant. The genotypic and phenotypic coefficient of variability estimated in the present investigations recorded high variability for almost all the characters except days to first green pods harvest, breadth of pods (cm), 100 seed weight and protein content per cent accompanied with high heritability and genetic advance indicating good scope for selection. Based on its contributing variability, heritability and genetic advance, breeders should give attention to the characters like plant heights, length of pods, length of internodes and days taken to first flower are important characters for bringing an improvement through selection of high yielding genotypes in garden pea.
