The aim of the present study was to evaluate the following parameters of maize grain yield: variability of inbred lines and their diallel hybrids, superior-parent heterosis and general and special combining abilities. According the obtained results of the two-year study, it can be concluded that variability of this trait is significantly affected by a genotype, year and their interaction. As expected, hybrids had higher average grain yields than inbreds due to the depression of this trait that occurs in inbreds during inbreeding. The highest average value of heterosis for grain yield was detected in the hybrid ZPLB405 x ZPLB406 (123.0% and 178.1% in 1997 and 1998, respectively).
