Abstract

An investigation was carried out with 48 genotypes of pea obtained through line x tester mating and were tested using a randomized block experimental design with three replications. The result showed a highly significant difference for all the 14 characters under study. The variability, heritability and genetic advance as percent mean were studied for all the characters. A high genotypic coefficient of variation was observed for the traits number of secondary branches, plant height, number of pods per plant, harvest index, nodules fresh weight and nodules dry weight. High heritability coupled with high genetic advance estimates was recorded for the number of secondary branches, plant height, pod length, number of seeds per pod, number of pods per plant, 100 seed weight, grain yield per plant, harvest index, nodules fresh weight and nodules dry weight indicating the role of additive gene action and selection for these traits could be reliable.
