In order to produce of new hybrids and evaluation of general and specific combining ability of sunflower inbred lines and restorers, 6 inbred lines and 6 restorer were selected in Z004. Aha107f81-108 and AhaI07f81-1Z0 inbred lines were erased caused by multi branch and having pollen, respectively. Finally Z4 fl hybrids were drived in 2004 and were evaluated on RCBD design with 3 replicatin in_ 2005. the results of variance analysis showed that treatments had significant differents for all traits except grain yield. RHa107F81-127/Z*Aha107f81-Z4o, Azargol and'RHa107F81-127/Z* A F81-3o had the greatest Grain yield with 4471,4274 and 4131 kg/ha, respectively. Variance Analysis of combining ability by designII of comestack and robinson showed that general combining ability of restorer and inbred lines for grain yield wasn't significant. Rha107f81-127/2 restorer and Ahaf81-120 inbred had the greatest general combining ability for grain yield. The results showed that Rha107f81-127/2 restorer has good potential to applicate in breeding programs.
