Abstract

A study was undertaken with F 1 and F 2 populations of 45 hybrids and their 10 parental populations to estimate the heritability and genetic advance. Observations of F 1 and F 2 populations were recorded for primary branches/plant, pods/plant, seeds/pod, 100-seed weight, seed yield/plant and harvest index. The estimates of high heritability were observed for 100-seed weight and pods/plant. The estimates of genetic advance (% mean)) were high for primary branches/plant, pods/plant and 100 seed weight. High heritability coupled with high genetic advance (%mean) were shown for pods/plant and 100-seed weight indicated that selection based on these traits was suggested for improvement in pea.
