This paper presents the results of seed processing of a maize hybrid seed composed of two commercial combinations produced on two locations in the same year. The charactersitcs of seed shape and size are separated into four fractions: flat seed (medium-small and small) and rounded seed (medium-small and small). The rounded seed fraction consists of a ball-shape and prismatic shape seed. A non-fractioned seed, i.e. the control fraction is also provided. The following seed characteristics are determined to be indicators: purity, mass of 1000 seeds, germination. Germination testing is performed under standard laboratory conditions. The experimental data are calculated as variation order. Differences among the averages are tested using-test. Single correlation coefficients are calculated for the characteristics. The results show that by separating the hybrid maize seed to different seed shape and seed size fractions can lead to uniformity of seed germination compared to a control fraction, as well as within the fractions.
