In order to produce new hybrids and evaluate the general and specific combining ability of sunflower inbred lines and restorers, four inbred lines and six restorers were selected in 2004. Twenty-four F1 hybrids were derived in 2004 and evaluated on a RCBD design with three replications in 2005. The results of variance analysis showed that treatments were significantly different for all traits except grain yield. RHa107F81-127/2 × Aha107F81-240 , Azargol and RHa107F81-127/2 × AHa107F81-30 had the highest grain yield with 4471, 4274 and 4131 kgha-1, respectively. Variance analysis of combining ability by design II of Comstock and Robinson showed that general combining ability of restorers and inbred lines for grain yield was not significant. Rha107F81-127/2 restorer and AhaF81-120 inbred had the greatest general combining ability for grain yield. The results generally showed that male parents or restorers play important role to produce hybrid cultivars and Rha107F81-127/2 has a good potential to be applied in breeding programs.
