Abstract: A field experiment was performed at the Arb El-Awamer Research Station, Assuit Governorate, Agricultural Research Center, Egypt during the two consecutive summer seasons of 2017 and 2018 to achieve the highest yield and good oil quality of nine tested sunflower genotypes. In both seasons, the experiment was conducted using the split plot design in randomized complete block design with three replicates arrangement keeping irrigation system (sprinkler and drip) in the main plots, and sunflower genotypes (L990, L770, L465, L125, L460, L880, L120, Giza 102 and Sakha 53) in the sub plots. Yield and quality traits were significantly influenced by irrigation system and genotypes as well as their interactions in both seasons and their combined analysis. The drip irrigation system seems to be a good compromise between the highest seed yield /fedden and good fatty acid composition of oil. Line 120 was ranked in the first order in head diameter, 100-seed weight, seed weight /plant, flowered late and hence seed yield /fedden, as well as seed oil content, whereas, Sakha 53 characterized with it contained the highest proportion of unsaturated fatty acids. The highest values of head diameter, 100-seed weight, seed weight /plant and hence seed yield /fedden as well as the highest proportion of unsaturated fatty acids composition were obtained by grown sunflower L120 at drip irrigation system.
