Abstract
The offspring of 6 maternal dent form lines (1566-5, 1573-2,1581-11, 1581-7, 1585-4, 1591-2) crossed with 8 testers (K182, K188, K194, K231, K296, K324, K376, S335) were investigated. The experiments were carried out at two locations (Kobierzyce and Smolice) with two replications using incomplete block design. Data were recorded for grain yield, dry matter content, lodging before harvest, tillering and smutted plants. Analyses of general and specific combining ability were done. Significant differences between environments for all studied traits were found. The interaction between GCA effect and environment was insignificant for grain yield, which is the valuable information for breeders. Insignificant interaction SCA effects with environment were shown for grain yield.
