Studies On Genetic Variability In Pea (Pisum sativum L.)

Abstract

Genetic variability was studied in 50 germplasms of pea (Pisum sativum L.). Wide range of phenotypic variability, genotypic coefficient of variation, heritability and genetic advance were observed in all the characters indicated large amount of variability among the genotypes for these traits. High heritability was accompanied by high genetic advance in plant height, seed yield per plant, number of pods per plant and days to maturity showing existence of additive gene action and selection may be effective. While, 100 seed weight, seeds per pod and days to flowering had high heritability with low genetic advance indicating, existence of non additive gene effect.
