Abstract: The experiment was conducted under rainfed condition at Agricultural Research Station, Madhira during early rabi 2016 using 35 blackgram germplasm lines along with four checks. Estimation of variation, phenotypic and genotypic correlations along with path analysis was calculated for the material under study. Days to maturity and plant height had positive significant correlation with number of clusters per plant, number of pods per plant, 100 seed weight, seed yield per plant and seed yield (kg/ha). Number of clusters per plant and number of pods per plant had positive significant correlation with other yield related traits. Path analysis revealed that number of pods per plant, 100 seed weight and seed yield per plant had positive direct effects coupled with positive significant correlation with seed yield (kg/ha). The above variables explain only very less percent of variability in seed yield per plant and hence some other factors which have not been considered here need to be included in this analysis to account fully for variation in seed yield per plant.
