Abstract:
The experiment conducted in three successive year’s during rabi 2020-21, rabi 2021-22 and rabi 2022-23 at Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur (C.G.) for estimation of correlation between yield and its component to study their direct and indirect effect on seed yield and oil content % in safflower (Carthamus tinctorius L.). Eleven morphological and qualitative traits were analyzed for phenotypic correlation among the traits as well as their direct and indirect effect. The correlation analysis results indicated that seed yield showed a positive significant association with harvest index % at phenotypic level which indicated that these traits are helpful in direct selection to improve the expansion of seed yield of safflower. The harvest index percent, biological yield per plant, days to maturity, plant height (cm), and number of primary branches per plant all had the greatest positive direct effects on seed yield, whereas days to 50% flowering, 100 seed weight, number of capitulum per plant, oil content (%) and number of seeds per capitulum showed negative direct effects. These suggested that breeding efficiency for seed yield in safflower will be improved by direct selection for these traits.
