In hybrid maize seed processing, due to variable and different agro ecological conditions in production, exist a problem of seed shape and size. Seed of different shape and size, beside physiological traits cause a problem in practice as planting material. First process to achieve planting value is to divide seed to different fractions of shape and size. In this paper, two single cross hybrids from Maize Research Institute Zemun Polje, have been studied. Seed was produced in two different locations. For each hybrid combination, two seed fractions were obtained for shape and three for size. For each hybrid combination and location, six different seed sizes were obtained. For each seed size, from hybrid combination and location, following seed characteristics were study: 1000 kernels weight, seed germination, kernel number per kilogram, kernel number and weigh by liter. Experimental data were calculated to total variability by factorial analysis of variance and correlation. Results shows similarity and differences in seed traits by seed size, location and hybrid combination. Of high significance are differences for kernel number per kilogram, kernel number and weight by liter. These results are of practical significance for hybrid maize seed processing
