A study was carried out to assess character association and genetic diversity among green gram genotypes. The results of correlation coefficient analysis revealed a significantly positive correlation for the traits viz., plant height, number of primary branches, number of clusters per plant, pod length, and number of seeds per pod with single plant yield. The path analysis revealed that the number of pods per plant, number of seeds per pod, and hundred seed weight had the highest positive direct contribution to single plant yield. Pod length showed a low indirect contribution to the total variance and all other traits showed a negative contribution to total variance.
