This paper presents the study on single cross hybrids of maize and their parental forms (inbred lines), at a density of 60.000 plants/hectare. During the period of vegetation were performed phenotypic observations for on six characteres (plant height, height of insertion of main ear, number of branches/ tassel, the total number of leaves/ plant, leaf length of the main ear, leaf width of the main ear), on a number of 5 plants from the central rows of each plot. Based on values obtained from leaf length of the main ear and leaf width of the main ear, it was determinated the foliar area of the leaf of the main ear. Plants were harvested individually to determine the ear weight, grain weight, ear length, kernel row number/ ear, kernel number/row, ear diameter, rachides diameter, the thousand kernel weight. Based on the obtained values were also determined kernel depth and kernel yield/ plant.
