In present study, 70 germplasm accessions of blackgram were evaluated for seven economically important characters. The study showed considerable variability for these characters. Heritability in broad sense was high for all the characters studied except for number of seeds/pod and pod length. High heritability coupled with high genetic advance as per cent mean was observed for plant height, number of clusters/plant, number of pods/plant, 100-seed weight and seed yield/plant. The association analysis revealed that the genotypic correlation coefficients were higher than corresponding phenotypic ones for all the character combinations. Number of clusters/plant, number of pods/plant, number of seeds/pod and pod length had a significant positive association with seed yield. Plant height and 100 - seed weight had a positive association with seed yield. Selection for high yield in blackgram could be made by inclusion of number of clusters/plant and number of pods/plant as selection criteria along with plant height.
