Abstract:
Higher GCV as well as PCV was recorded for days to flower bud initiation, days to 50 per cent flowering, number of inflorescences per plant, number of flowers per inflorescence and L-DOPA yield per plant. High heritability estimates were coupled with high genetic advance as percent of mean was recorded for number of leaves at harvest, leaf area at harvest, days to 50 per cent flowering, number of inflorescences per plant, number of flowers per inflorescence, total dry matter production per plant, test weight of seeds, seed yield per plant and L-DOPA yield per plant. The correlation studies reveled that genotypic correlation was higher than the phenotypic correlation for most of the traits studied indicated that high heritable nature of the characters. seed yield per plant showed highly significant and positive correlation with number of trifoliate leaves per plant (0.906, 0.786), leaf area at harvest (0.822, 0.689), number of days to flower bud initiation (0.755, 0.651), days to 50 per cent flowering (0.758, 0.641), number of inflorescence per plant (0.760, 0.713), number of pods per bunch (0.973, 0.868) and pod yield per plant (0.998, 0.757) and L-DOPA yield per hectare (0.873, 0.869) both at genotypic and phenotypic levels, respectively. L-DOPA yield per hectare (1.517) exhibited high direct positive effect on seed yield followed by days to 50 per cent flowering (1.141) and leaf area at harvest (0.531). Seed yield per plant (1.066) exhibited maximum positive direct effect on L-DOPA yield followed by number of trifoliate leaves per plant (0.818) and test weight of seeds (0.293).
