The aim of this paper was to investigate the genetic variability and the mode of inheritance between inbred lines and their hybrids, for three very important traits, ear height, cob weight and grain yield. Nine inbred lines are domestic germplasm made at the Institute of Field and Vegetable Crops in Novi Sad, Serbia, and four are from USA. Statistical data analysis shows genetical variability between inbred lines for every analysed trait. Superdomination was mode of inheritance for ear height and grain yield, found in every observed combination. Obtained results confirmed superdomination and domination as mode of inheritance for cob weight. Highly positive correlations were determined between ear height and grain yield, cob weight and grain yield, and cob weight and ear height.
