Abstract: Pea (Pisum sativum L.) is a grain legume crop grown globally for human consumption and good source of protein. An experiment was conducted in augmented randomised complete block design to estimation of genetic variability, heritability and genetic advance in field pea among fifty-four genotypes with twelve traits. The ANOVA results indicated substantial variations among the genotypes for all traits, demonstrating a broad spectrum of variability among them. The result shows that found were highly significant for the trait Days to 50% flowering, Number of pods per plant, Number of seeds per pod, 100 seed weight (gm) and Yield per plant (gm) Days to Maturity, Plant Height (cm) and moderately significant in the characters Number of Primary branches per plant, Pod length (cm). These traits which are superior and used to select cultivars for yield augmentation showed the highest values of genetic variability (PV 27.01, 25.74) and genetic coefficient of variation (GCV 5.89, 5.56) among harvested traits; while the lowest heritability (15.38%) and Genetic advance as a percentage of mean was classified as high genetic advance (>20%), medium genetic advance (10%-20%) and low genetic advance (<10%) 2025The highest percent of mean genetic advance was recorded for biological weight (50.60 %), days to maturity (27.86 %) and plant height (17.91 %) low genetic advance values was observed for the number of seeds per plant (5.48%), harvest index (5.07%), number of seeds per pod (5.06%), days to 50% flowering (4.85%), seed yield per plant (4.34%), 100-seed weight (2.18%).
