These experiments were conducted in two different sites to study the genetic variability and the mean performance of the elite different origin maize genotypes under irrigated condition in central of the Sudan on rainy season 2014. The experiments were arranged in randomize complete block design in three replicates, the data were collected on days to 50% tasseling and silking, plant and ear height, ear length and diameter and grain yield. The analysis of variance for each site and a cross sites showed a significant variability among tested genotypes for grain yield, days to 50% tasseling and silking, plant and ear height, ear length and diameter. Also, significant different were observed for genotypes, site and a cross site for most of studied traits such as for grain yield, days to 50% tasseling and silking, plant and ear height, ear length and diameter. The combined results for genotypic coefficients of variability and broad sense heritability estimates grain yield, ear length and ear diameter varied significantly among the tested genotypes.
