Character association and path analysis studies at genotypic level on some genotypes of safflower (Carthamus tinctorius L.)

Safflower is one of the old domesticated crops and mostly cultivated for oil purpose. Large numbers of variability were found in this crop and through the successful breeding programme the problems can be eradicated. The experiment was conducted at BTC College of Agriculture and Research station, Bilaspur (C.G.) in Rabi season during 2017- 18.The experimental material consisted of a population of 26 genotypes included two checks A1 (NC) and PBNS-12 (C) with laid out in Randomized block design. Genotypic correlation studies show that seed yield had exhibit highest significant positive correlation with harvest index (0.806) followed by Biological yield (0.801), 100 seed weight (0.677), volume weight (0.563), branches /plant (0.474). Whereas non -significant but positive with rosette period (0.360), plant height (0.351), days to maturity (0.324), days to flowering (0.306), capitulum per plant (0.285), seeds per capitulum (0.254). At the genotypic level path analysis results shows that seed yield had maximum direct positive effect with biological yield (0.682) followed by harvest index (0.524), rosette period (0.087), capitulum per plant (0.056), plant height (0.012). Whereas 100 seed weight (-0.100), days to 50% flowering (-0.050), branches per plant (-0.042), days to maturity (-0.035) seeds per capitulum (-0.037) volume weight (-0.016) had negative direct effect on seed yield. | Character association and path analysis studies at genotypic level on some genotypes of safflower (Carthamus tinctorius L.)
