Abstract:
The present study was aimed to analyse the cause and effect relation between the yield related traits in RIL population developed from the cross CO-1 x EC-523368-2 during rabi 2020-21. The path analysis resulted with traits number of seeds per primary capitulum, number of primary capitula per plant showing positive direct effect while days to 50% flowering has shown negative direct effect. The indirect effect on seed yield was attributed by days to 50% flowering via days to maturity, number of primary capitula per plant via number of seeds per primary capitulum. However, the traits showing strong direct effect were strongly correlated with the seed yield. Hence, selection of genotypes based on these traits would be reliable in the crop improvement programmes.
