Correlation and path-analysis in 49 cultivars of mustard (B. juncea L.) and rapeseed (B. campestris L.) were done for plant height (PH), primary branch/plant (PB/P) and secondary branch/plant (SP/p), (YP). At phenotypic level all the characters showed positive and significant correlation with yield except SB/P. The phenotypic correlations were also highly significant and positive in between PH and PN/P, PB/P and SN/P and SB/P and SN/P and in between PN/P and SN/P. The genotypic correlations were lower than the phenotypic correlations and the associationwere negative in nature. The genotypic correlation was negatively significant in between YP and PH. Path-analysis revealed the PN/P and SN/P had the highest direct effects and PB/P had indirect effects on yield via PN/P and SN/P respectively
