Abstract
In this paper the agronomic value of 110 maize hybrids included into preliminary grain trials carried out in 1999 and 2000 in 5 localities was studied. Out of these, 36 hybrids were tested in both years. The trials were preformed in a lattice design on 10 m2 two-row plots in three replications. The yield of grain in dt/ha at 15% moisture content and dry matter content in grain at harvest were evaluated. For 36 hybrids tested in both years the data are presented in three tables as mean values obtained in each year of testing and as a two-year average. Based on the results obtained, the best twelve hybrids were applied for the official trials in 2001.
