For selection the most suitable hybrids,13 sunflower single cross hybrids, derived from crosses between CMS (Pet) lines and Restoren lines plus Azargol and Ketil hybrids, as check varieties, 15 treatments, were evaluated in 4 locations ( Karaj, Isfahan, Gonbad, and Zarghan) at 2 years (2004-2006).These treatments were executed in Randomized Complete Block Design with 4 replications. Simple Data analyses and means comparison for some important traits were made. Agronomic traits included phenological characters, plant .height, head diameter, were recorded during growing season. Oil percentage, and 1000 seed weight and economical traits as seed yield and oil yield (Kglha) recorded after harvesting. In first year in Karaj, Isfahan, and Gonbad CMS19*R-1031, was. the best combination, but in Zarghan results were different from another's. Combined Analysis of Variance for locations showed that CMS19*R-1031, and CMS14*R-43 were the better than control hybrid Azargol; In second year the Zarghan was omitted from executed locations. In this year results were different for every location, but C.A. of V. for 3 locations revealed the most. suitable hybrids were CMS19*R-1031, CMS14*R-43 which had not significant difference with AzargoL At the end of second year C.A. was made for 2 years and 3 locations. Results showed that CMS19*R-1031(3475Kglha 93 days duration), C\}\\fS14*R-43(3238Kglha) were the best one but had Q.ot any signifi~ant difference with Azargol (3088Kglha). The fint one CMS19*R-1031, was earlier than another combination and would be. selected.
