  Marakan protected region with an area of 105069 ha, is located in North West of Iran (west Azerbaidgan province), between 38 42` to 39 6` north latitude and 45 5` to 45 37` east longitude. In this study flora of this region was determined by using available references. We encountered 282 Species that belongs to 167 Genera and 47 Families. The largest families of region are: Asteraceae with 43 species, Fabaceae with 28 sp., Poaceae with 26 sp. and Rosaceae with 25 sp. The life form spectrum was characterized according Raunkier`s system. The life form spectrum observed was: Therophyte 31.91%, Hemichryptophyte 26.95%, Chamaephyte 16.31%, Phanerophyte 15.06% and Cryptophyte 9.26%. The phytocorya distribution of species are as follow: IT 65.25%, Es 5.31%, Med 1.06%, IT, Es 19.15%, IT, Med 2.85%, Es,Med 1.78%, Endm 4.25%, Cosm 0.35%.

  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.
