Abstract
The variability and gene effects for boron (B) concentration in wheat leaves at heading were evaluated on the basis of generation mean analysis. The epistatic gene effect was tested using the six-parameter model. Six basic generations (P1, P2, F1, F2, BC1, BC2) of three crosses were studied. The lowest B concentration was found in 'Rodna' (6.2 ppm), which was the most B-efficient genotype. The highest mean value for B concentration was found in the Russian genotype 'Bezostaya 1' (16.6 ppm). The mode of inheritance in the F1 and F2 generations was different (intermediate, dominant, superdominant) depending on the cross combination. B concentration in wheat leaves was under the control of the genes with additive, dominant and epistatic effects (a x a, a x d, d x d). Breeding B-efficient wheat genotypes could be interesting for the region of Vojvodina (the northernmost part of Serbia and Montenegro), where there are saline soils, as it is known that high B concentrations may cause problems, especially in interaction with drought stress problems
