Grain yield was significantly correlated with number of primary branches plant⁻¹, number of secondary branches plant⁻¹, plant height, number of capitula plant⁻¹, number of effective capitula plant⁻¹, number of seeds primary capitulum⁻¹, number of seeds secondary capitulum⁻¹, seed to hull ratio, and biomass. Path coefficient analysis revealed that number of capitula plant⁻¹, number of seeds secondary capitulum⁻¹, days to maturity and biomass had highest positive direct effect on grain yield. Improvement of the grain yield can be efficient via number of capitula plant⁻¹, number of seeds secondary capitulum⁻¹, days to maturity and biomass based selection.
