Abstract: Present study was conducted to estimate relationships among seed yield components in in F_3:4 population in safflower using simple correlations. The recurrent selection experiments are mainly designed and conducted for improving seed yield plant'¹. The plant height showed no correlation with flowering, branch number, capitulum number, seed number, oil content and seed yield per plant. Days to 50% flowering was negatively correlated with seed yield per plant (r=-0.189**), test weight (r=-0.303**) and seed oil content (r=-0.166**).Branch number and capitulum number per plant showed highly positive correlation (r=0.999**) with each other, which were also positively associated with seed yield per plant (r=0.236**).Seed number per capitulum was negatively correlated with test weight (r=-0.235**).Test weight showed positive correlation with seed yield per plant (r=0.399**) and seed oil content (r=0.203**) while it was negatively correlated with days to 50% flowering (r=-0.303**) and seed number per capitulum (r=-0.217**). Seed oil content was positively correlated to test weight (r=0.203**) and negatively correlated with days to 50% flowering (r=-0.166**).Seed yield per plant was positively correlated with branch number (r=0.235**), capitulum number (r=0.234**) and test weight (r=0.399**) while it was negatively correlated with days to 50% flowering (r=-0.189**). A critical analysis of direct and indirect effects in F_3:4 population indicated that test weight had the maximum direct positive effect (0.3031) on seed yield per plant followed by capitulum number (0.2167) and seed oil content (0.1428), which may be considered.
