Abstract:
The present experiment was conducted at the Research cum Instructional farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, during rabi 2020-21 with a view to study the phenotypic correlation and path analysis studies for yield and yield contributing traits in safflower. 16 safflower genotypes along with 3 checks viz., A1 (NC), DSH-185(HC), PBNS-12(VC) were evaluated. Association studies indicating positive association of harvest index and biological yield for seed yield as dependent trait, and shows negative association for traits like number of branches per plant and oil content. The oil content had significant negative correlation with harvest index and seed yield. Thus these characters are the key yield contributing characters to be given selection pressure for improving yield. The result of path analysis indicated that the characters biological yield, number of capitulum per plant and 100 seed weight showing direct effect on yield. Highest positive direct effect on oil content was recorded for traits like number of capitulum per plant and biological yield.
