Abstract: This experiment with nine genotypes consist of 8 sunflower hybrid along with Record cultivar were sown in a randomized complete block design with 4 replication at the experiment farm of uremia university in 2004. Twelve quantitative traits (Days to 50% flowering, days to physiological maturity, plant height, number of leaves per plant, head diameter, number of filled seed per head, 1000 seed weight, kernel percentage, unfilled seed percentage, oil percentage, seed tiled, oil yield) were evaluated and measured. Among evaluated traits, number of filled seeds/head (0.754**) 1000 seed weight (0.732**) and head diameter (0.723**) had highest positive and significant correlation with seed yield and seed yield (0.843**) had highest positive and significant correlation with oil yield. Stepwise regression for seed and oil yield indicated that five traits including number of filled seed/head, 1000 seed weight, head diameter, oil percentage. Regarding the direct and indirect effects of each effective traits in oil and seed yield, it seems that screening with emphasis of the number of filled seeds/head, 1000 seed weight and head diameter could be effected on maximum.
