The main purpose of this research was to estimate combining ability for fifteen white inbred lines of maize via line × tester mating design. 15 inbred lines were crossed with two testers. The resulting 30 crosses with three commercial checks were evaluated in a randomized complete block design with 4 replications at two locations: Sakha and Sids Res. Station in 2018 season. Analysis of variance showed existence of variability among genotypes. Additive gene effects had the important role in the inheritance of most studied traits. The cross Sk5008/75 × Sk-13 (38.1 ard/fad.) did not significantly outyield the three commercial checks. The tester Sk-13 was favorable combiner than Sk-8 for most of studied traits. The best inbred line for general combining ability effects was Sk5008/76 for earliness, Sk5007/74 for plant and ear heights, Sk5008/75 for grain yield, Sk5008/79 for ear length and Sk5008/81 for ear diameter.
