ABSTRACT

Thirty one advance lines including six varieties of pea were studied for genetic variability, heritability, genetic advance and character association for seed yield/plant and related attributes. The maximum variability was observed for seed yield/plant followed by pods/plant, plant height, branches/plant and 100-seed weight. Heritability estimates were found to be high for all characters except days to flower and pod length in broad sense. High expected genetic advance coupled with high heritability estimates were predicted for seed yield/plant, pods/plant and plant height indicating least influence by the environmental variation. Seed yield/plant had significant and positive association with pods/plant, plant height, harvest index and grains/pod.
