Abstract
Correlation coefficient and path analysis studies were carried out with seventeen parents (fourteen lines
and three testers) resulting 42 F1 crosses for fifteen yield contributing component characters. The phenotypic and
genotypic correlation analysis revealed that seed yield was highly significantly and positively correlated with number
of branches, number of clusters, number of pods per plant, number of seeds per plant pod weight, total biomass and
also highly significantly and positively correlated among themselves. Path coefficient analysis for seed yield revealed
that significant phenotypic and genotypic direct effect with seeds per plant, 100 seed weight, harvest index, pod
weight and number of clusters per plant. Hence selection for these characters may be carried out in the field and lab
for overall yield improvement in blackgram.
