Highly significant genotypic differences were recorded for all the traits which implies that there is a considerable amount of variation present among genotypes for each character. The phenotypic variance was more than genotypic variance, and also the phenotypic coefficient of variation was higher than genotypic coefficient of variation which indicates more role of environment on the studied traits. Estimates of heritability were higher for almost all traits, except number of branches plant-1. Moderate value of genetic advance was observed for grain yield plant-1 and the remaining traits recorded least value of genetic advance. High heritability along with high genetic advance indicated the prevalence of additive gene effects. Thus, the selection program based on these traits would be more effective in improving yield parameters of pea. The additive genetic variance in appearance of these characters can be useful in hybridization and selection for higher pod yield in pea
