Abstract

Fifteen yellow inbred lines of maize were crossed with three yellow inbred testers Gz664, Gm 6061 and Gm 6042 to produce 45 hybrids during summer, 2015 at Gemmeiza Research  Station. In summer season, 2016 the 45 hybrids and the three checks were evaluated under two locations i.e Gemmeiza and Nubaria Research Stations. The rustles of these studies can be summered that: mean squares of crosses and their  partitions (lines, testers and lines x testers) showed highly significant for all traits under this study except, crosses, line, tester and line x tester mean squares for ear length and ear diameter under two locations. The additive and additive x additive gene actions played more important in the inheritance of ear length at Nub. Location and ear diameter at both locations, Non- additive gene effects played an important role in the  inheritance of days to 50% silking, plant and ear heights and grain yield at both locations and ear length at Gemmeiza location. Regarding Gm 17 had negative and significant GCA effect in Gemmeiza location for plant and ear heights and positively significant for grain yield in both locations, For Gm 19which had positively significant GCA effect for grain yield in both locations Gm 37 had negatively significant GCA effect for days to 50 % silking in both locations and positive and significant GCA effect for grain yield in both  locations. For grain yield, the three crosses (Gm17 x Gm 6061), (Gm22 x Gm 6042) and (Gm36 x Gm 6042) had positively highly significant SCA effects in both locations .
