Abstract:
The present investigation was carried out during Rabi season 2015-16 to study the genetic parameters, genetic variability, heritability and genetic advance for 62 pea genotypes.This experiment was laid out at Research Farm ofInstitute of Agricultural Sciences, Banaras Hindu University, Varanasi in a randomized block design with three replications. Data were recorded for ninecharacters. Analysis of variance revealed that the highly significant differences are present among the genotypes for all the characters under study. The genotypes exhibited wide range of variability for most of the traits. The genotype IC-203386, IPF-9931, PANTP-14 and IC-267182 showed high mean performance for yield. The analysis of genetic parameters revealed higher phenotypic and genotypic coefficient of variation was found for character plant height (1186.10% and 1152.77%) while moderate PCV and GCV found for characterobservation traits pod perplant(4.09%and3.15%),25seed weight(0.52%and0.40%), seed yield perplant(1.61%and1.26%), pod length(0.39% and 0.33%), number of primary branches(0.09% and 0.028%) and seed per pod(0.41% and 0.21%). High heritability coupled with higher estimates of genetic advance as a per cent of mean observed for characters plant height, 25 seed weight, seed yield per plant, pod length and pod per plant, shows that simple selection could be practiced for improving these characters.
