Abstract

Forty advance lines including five varieties of pea were evaluated for eleven quantitative characters. The highest genotypic coefficient of variation was observed for seed yield/plant followed by number of branches/plant, number of pods/plant and plant height. Heritability estimates (broad sense) were found to be high for all characters except number of grains/pod. High expected genetic advance coupled with high heritability estimates were recorded for seed yield/plant, number of branches/plant and number of pods/plant indicated least influence by the environmental variation. Biological yield/plant, harvest index, pods/plant, branches/plant and grains/pod were significantly correlated with seed yield/plant. The studies suggest that the selection pressure should be exercised simultaneously for high biological yield and harvest index, more number of pods and branches/plant.
