Comparison was made between 22 new maize hybrids from Hodowla Roślin Smolice Sp. z o.o. The plots were established within trial program of five experimental stations located in 2008, in different soil and climate conditions. The results were compared with mean of three COBORU (Research Centre for Cultivar Testing) standards. Within 22 tested hybrids, four of them (no. 6 – SMH 0827, no. 14 – SMH 0835, no. 13 – SMH 0834 and no. 8 – SMH 0829) had yielded significantly higher than mean of standards, and one of them (no. 3 – SMH 0824) had significant higher dry matter content than mean of standards. Two hybrids: no. 18 – SMH 0839 and no. 24 – PR39H32 (standard) showed break of negative correlation between yield and dry matter content in kernels as their average yields and dry matter content were higher in all cases. Based on Kanga’s measurement and standard deviation procedure, genotypes were selected according to suitability for particular growing regions. The best yielding and stabile hybrids are: no. 14 – SMH 0835 and no. 6 – SMH 0827. The best and stabile dry matter content had: no. 1 – SMH 0822, no. 3 – SMH 0824, no. 11 – SMH 0832 and no. 22 – SMH 0843. Hybrids no. 6 – SMH 0827 and no. 18 – SMH 0839 were selected for testing investigation in COBORU.
