A small number of nations produce sunflower on a big scale; including the Turkey (Mediterranean Region, Central Anatolia, Thrace). The recent development of the production is quite impressive in the Eastern part of Europe and in Turkey. Breeders of sunflowers aim to develop genotypes that perform well and are adaptable to a wide range of conditions. Along with seed yield, sunflower seed oil content must be increased to meet industrial requirements. This study was conducted in three locations at two different geographical regions in Turkiye (Thrace and Cukurova Regions), in the 2015 growth season. As a result of the study, plant heights (cm), table diameters (cm), 1000 seed weights (g), seed yields (kg ha-1), seed oil contents (%), seed protein contents (%) and oil yields per ha (kg ha-1) were determined between 112.0-150.6 cm; 15.21-20.09 cm; 54.9-79.9 cm; 3198-4148 kg ha-1; 38.94-42.42%; 15.47-18.69%; and 1287-1631 kg ha-1, respectively. As a conclusion, Genotype no 1, 2, 3 and 4 were found superior in terms of yield in the trials.
