The analyses were performed with the hybrid seeds of four hybrid combinations derived at the Maize Research Institute, Zemun Polje and produced in three locations. Under laboratory conditions, the following seed traits were analysed in the working sample of 10x100 seeds: seed test weight and shelling percentage, which was determined as the seed weight to ear weight ratio. In the three- year study, the greatest (352.71 g), i.e. smallest (280.09 g) test weight was recorded in the hybrids ZP 434 and ZP 704, respectively. The highest shelling percentage of 60.53 % was determined in the hybrid ZP 704, while the lowest one (48.20 %) was recorded the hybrid ZP 434. Obtained results point out that both traits in all four hybrids are highly expressed under all observed agro-ecological conditions and that effects of factors on the seed weight and the shelling percentage are great.
