Abstract
The aim of the study was to evaluate combining abilities of inbred maize lines. The experimental material consisted of 6 female lines and 4 male lines (flint types). The experiment was carried out in two localities (Kobierzyce and Smolice) using a randomized block design with two replications. Lodging at harvest, smut resistance, dry matter content and grain yield were evaluated. The analysis of variance showed significant differences between localities in all the traits as well as difference in three traits within Kobierzyce, and in two traits within Smolice localities. The analysis of combining ability showed significant interaction of GCA with the environments, affecting dry matter content, and of SCA with the environments, influencing dry matter content and grain yield. A female line 1294-7 and hybrids 1375-5 × S41324A-2, 1360-5-1 × Co255, and 1044-87 × K154 were distinguished as the most valuable forms.
