Fourteen white maize inbred lines derivative from diverse heterotic group by choice in field disease at Sids Agricultural Research Station were used in this study. In 2014 growing season, the fourteen white maize inbred lines were crossed with two testers Sids 7 and Sids 1157.  In 2015 season 28 white single crosses and two checks (SC 10 and SC 128) were assess at two locations (Gemmeiza and Sids). Statistics were registered for five traits [days to 50% silking, plant and ear heights (cm.), ear length and grain yield (ard/fad)]. Collective analysis over two locations revealed that mean squares for crosses, lines, testers and lines × testers were significant and highly for all the studied traits, except lines × testers mean squares for days to 50% silking and ear length. Mean squares for crosses × locations interactions were highly and significantly for all the traits studied, except ear length. Mean squares due to lines × locations had significantly and high for days to 50% silking. Testers × locations interactions had highly and significant for all studied traits. The magnitude of σ² GCA was larger than that σ² SCA for all traits. For grain yield, two crosses (L7 × Sd 7 and L13 × Sd7) considerably out yielded the best commercial check SC 128. The best GCA effects were obtained from three inbreed lines (L5, L7 and L13) for grain yield. Two top crosses (L1 × Sd 1157 and L11 × Sd 7) had positively significant SCA effects for grain yield.
