The present work was carried out with blackgram accession IC436524, collected from NBPGR regional centre, Hyderabad and T-9 variety was collected from ICAR-CRIDA, Hyderabad. Correlation analysis reveals the extent to which individual attributes are linked to output, providing a measure of the connection between traits. The correlation analysis results revealed that among ten quantitative characters, number of seeds/plant was phenotypically and genotypically significantly correlated with seed yield followed by plant height (cm), number of clusters per plant, number of pods per plant, number of leaves per plant, 100 seed weight (g), number of branches per plant. The correlation results revealed that significant association (genotypic and phenotypic) between and among the most important traits viz., pods, clusters per plant, seeds and seed yield per plant. The heritability and Genetic advance estimations results revealed that the maximum heritability, Genetic advance mean value (%) recorded for the character seed yield, numbers of pods per plant and seeds per plant, clusters per plant and pods. The results also revealed that most of the characters under study were recorded higher PCV than GCV which indicates little environmental influence on the characters in the Blackgram mutants in M3 generation.
