Eight sunflower inbred lines and 15 F1 hybrids (line x tester) have been analysed for correlations between several seed characteristics (husk content, kernel content, number of seed per head, weight of 1000 seeds, mass of 1 hl) and seed yield per plant. The path-coefficient analysis was employd to partition the direct and indirect effect of the studied characteristics on seed yield per plant. Highly significant positive correlations were found between number of seed per head, weight of 1000 seeds and seed yield per plant. Highly significant but negative correlations were found between husk content and kernel content. Number of seeds per plant had a significant positive correlations with weight of 1000 seeds whereas the weight of 1000 seed had a significant negative correlation with mass of 1 hl. Number of seeds per head exhibited a highly positive direct effect on seed yield, whereas the weight of 1000 seeds has less positive direct effect. Husk content and kernel content had highly negative direct effect on seed yield.
