Abstract

Phenotypic and genotypic coefficients of variability, heritability (broad sense), gene- tic advance, correlations and path coefficients were studied in 20 strains of blackgram Vigna mungo (L.) Hopper). Pod length and plant height were found to have high gonotypic coefficients of variation, heritability and genetic advance, High heritability in conjunction with low genetic advance was obtained for seeds per pod 100-seed weight and pods per cluster. The grain yield per plant showed significant positive correlation with number of branches, pods and clusters per plant. Path analysis revea'ed that clusters per plant had maximum positive direct effect on grain yield and it was followed by pods per plant.
