In this study, diallel cross method were used to determine general and specific combining ability of maize lines produced in Safiabad Agriculture Research Center (SARC). For this purpose 32 maize lines were crossed in four separately diallel cross each one with 8 lines in 2008. At all (4×56=224) F1 hybrid produced which evaluated and comparison together and with SC704 hybrid as local check using (RCBD) with three replications in 2009. Significant differences were observed between crosses in four diallel for yield characteristics at one percent level. Results showed that in first diallel cross the cross number 47 and 23 with 9.19 and 8.77 tons grain per hectare respectively; in the second diallel cross the cross number 13 and 11 with 8.01 and 8 tons grain per hectare respectively; in the third diallel cross the cross number 11 and 16 with 10.63 and 10.17 tons grain per hectare respectively and in the forth diallel cross the cross number 46 and 36 with 8.64 and 8.53 tons grain per hectare respectively were in a class and better than local check SC704 with 4.7 tons grain per hectare.
