Abstract: Twenty diverse cultivars of pea grown in a Completely Randomized block design (CRBD) at AKS University, Satna, during Rabi season on November 2022. Data were collected for ten quantitative traits and estimated for variance, genetic variability, heritability and genetic advance. The design of the experiment indicated highly significant differences for all the characters due to treatments. The analysis of variance indicated the existence of sufficient amount of variability among genotypes for all the studied characters. The maximum GCV along with PCV was observed in number of pod per cluster followed by seed yield per plant, 100 seed weight (g), number of seed per pod and number of pods per plant. Higher estimates (h2b) >80% were observed for Seed yield per plant followed by 100 seed weight (g), plant height (cm), days to maturity, days to 50 % flowering, pod length, shelling (%) and number of seed per pod. High estimate of expected genetic advance at 5% were found for number of pod per cluster followed by seed yield per plant, 100 seed weight (g), number of seed per pod and number of pods per plant. High heritability coupled with high genetic advance indicated the predominance of additive gene action in the expression of these traits.
