Estimation of genetic variability, heritability and genetic advance for yield and its components in Pea (Pisum sativum L.)

Abstract

Genetic variability, heritability and genetic advance as percent over mean for nineteen quantitative traits of pea germplasms were assessed during rabi season 2017-2018 under Pea Improvement Project at Seed Breeding Farm, Department of Plant Breeding and Genetics, J.N.K.V.V., Jabalpur, (M.P.).High value of PCV and GCV was recorded high for number of pods per plant followed by number of effective nodes per plant, number of seeds per plant, number of nodes per plant. High heritability coupled with high genetic advance as percentage of mean would offer better scope of selection for number of pod per plant followed by number of effective nodes per plant, number of seeds per plant, number of effective pod per plant, number of nodes per plant, seed yield per plant, number of primary branches per plant, number of secondary branches per plant.
