The experiment was carried out to determine the genetic variability parameters and character associations for eleven quantitative traits in Indian bean genotypes. It revealed a significant amount of variability present among these genotypes. Seed yield per plant had high Genotypic coefficient of variation (GCV) and Phenotypic coefficient of variation (PCV) values, showing the potential for improvement by selection. Racemes per plant, pods per raceme, pods per plant, and pod weight had moderate GCV and PCV values. There was high heritability combined with a high genetic advance for pod weight and seed yield per plant. Plant height, pods per plant, and pod weight were significantly and positively associated with seed yield per plant. Pods per plant had the most positive direct effect on seed yield per plant, followed by racemes per plant, plant height, pod weight, pod length, and seeds per pod. Therefore, selection for such traits is advised to bring about improvement in Indian beans.
