Abstract

Twenty two field pea genotypes were evaluated for estimation of variability, heritability and genetic advance. The Fieldpea genotypes were sown in, Randomized Block Design with three replications at the experimental farm of department of Genetics and Plant Breeding, Faculty of Agriculture, Kamla Nehru Institute of Physical and Social Sciences Sultanpur 228118 (U.P.) India, during Rabi, season 2022-2023. Phenotypic data were recorded for nine characters viz. days to 50% flowering, days to maturity, plant height, number of branches per plant, number of pods per plant, 100-grain weight, grain yield per plant and biological yield per plant. It was reported that in general the value of phenotypic coefficient of variance (PCV) is slightly higher than the value of genotypic coefficient of variance (GCV) indicating the importance of environment in the phenotypic performance of the genotypes studied. The maximum value of GCV was observed for plant height (31.94), grain yield per plant (20.02). High estimates of heritability in broad sense (h2b) were recorded for plant height (97.28), days to 50% flowering (83.96), 100-grain weight (78.48) and days to maturity (64.83). High estimates of genetic advance as percent of mean were recorded for plant height (64.89), 100-grain weight (25.28) and grain yield per plant (25.15). Thus, the characters (plant height, days to 50% flowering, 100-grain weight etc) having high value of GCV, heritability as well as genetic advance may be exploited in Fieldpea breeding program for further improvement in grain yield.
