Abstract

Eight yellow maize (zea mays L.) inbred lines were crossed in half diallel mating scheme in 2013 season at Gemmeiza Agric. Res. Station giving a total of 28 crosses as hybrid seeds. In 2014 summer season, these 28 crosses were evaluated in a randomized complete blocks designs experiment with four replications at two locations and two densities i.e. 20 cm (D1) and 25cm (D2). Gemmeiza (L1) and Mallawy (L2). The whole study was designated as four different environmental conditions (L1D1, L1D2, L2D1 and L2D2) in each experiment. location mean squares had significant and high significant for  days to 50% tasseling, plant height, ear height, ear length, number of rows / ear, number of kernels / row and grain yield (ard / fad. ) at D1 and D2. While, ear diamater and 100-kernel weight  at D1 and days to 50% silking at D2 had significant location mean squares. Mean squares of densities  exhibited  significant and high significant for  days to 50% tasseling and silking at L2 and ear diameter at L1. While,  plant and ear heights, ear length, 100-kernel weight and grain yield / fad. had significant mean squares of densities, indicated that these traits changed their performance from location to another. Crosses mean squares were high significant for all traits under locations and densities meaning that, differences among the crosses under locations and densities were exited. Crosses x locations interaction mean squares had highly significant for days to 50% tassling, days to 50% silking and ear height at D1. Crosses x densities interactions mean squares had significant  differences at  four environments for most traits The interactions between crosses with the partitions; locations (L), densities (D) and (L x D) were significant for all traits,  meaning that the crosses were affected by change of locations, densities and interaction of  locations x densities.
