Abstract: The present investigation entitled “Estimate of variability, heritability and genetic advance with respect to yield and yield contributing characters in field pea (Pisum sativum L.)” for 10 characters. The experiment comprising of 23 genotypes of pea were grown in a Randomized Block Design (RBD), with three replications at Research Farm, Department of Genetics & Plant Breeding, Post Graduate College, Ghazipur, during rabi season of 2017-2018, plant to plant and row to row distance was kept 10 cm and 45 cm, respectively. The estimates of genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) and environmental coefficient of variation (ECV) showed a wide range. It indicates that considerable amount of variability was present in the material. The high estimates of genotypic coefficient of variation (GCV) were observed for plant height, biological yield per plant, number of pods per plant, seed yield per plant, number and 100-seed weight. Moderate estimates of GCV were observed for days to 50% flowering, pod length and number of seed per pod. Whereas, low GCV were observed for harvest index and days to maturity. The high estimates of phenotypic coefficient of variation (PCV) were observed for seed yield per pod, number of pods per plant, biological yield per plant, harvest index, plant height. Moderate estimates of PCV for 100-seed weight, pod length and number of seed per pod. Whereas low PCV were observed for days to 50% flowering and days to maturity. The estimates of heritability in broad sense were high for plant height, days to maturity, days to 50% flowering, 100-seed weight, biological yield per plant. Moderate estimates of heritability were observed for number of pods per plant, number of seed per pod and pod length. High estimates of genetic advance were observed for plant height, biological yield per plant, days to 50% flowering and number of pods per plant. Moderate estimates of genetic advance were observed for. 100 seed weight, days to maturity and seed yield per plant. Whereas low genetic advance were observed for pod length, number of seed per pod and harvest index.
