The genotypes differed significantly for all the characters under study. Higher genotypic and phenotypic coefficient of variation was observed for secondary branches per plant, primary branches per plant, pods per plant, grain yield per plant. Genetic advance was highest for plant height followed by days to maturity and pods per plant. High heritability coupled with moderate genetic advance was observed for plant height, days to maturity, pods per plant, protein content, days to 50 percent flowering, secondary branches per plant, grain yield per plant, primary branches per plant. grains per pods, 100 grain weight, plant height, days to 50 percent flowering, plant height, days to maturity, primary branches per plant and secondary branches per plant was significantly and positive association with grain yield per plant. It was apparent from the path coefficient analysis that maximum direct effect as well as appreciable indirect influence were exerted by pods per plant, 100 grain weight. These suggested that emphasis should be given to these traits in selection program for improvement of seed yield in green gram.
