The relationships between seed yield and some morpho-physiological parameters, such as plant height, head diameter, leaf number, number and weight of total and full seeds per head and 1000 seeds in 32 local hybrids has been studied. The analyses of Pearson correlation coefficients showed significant, but low, positive correlations between yield and number of full seeds per calatidium, weight of total seeds per calatidium, weight of 1000 seeds and hectolitre weight. There were also observed positive correla-tions between plant height and number of leaves.
