Barley doubled haploids covering a wide range of malting quality, along with their parental cultivars and F2, F3 hybrids, were investigated in six environments (three locations, two years) to study the genotype-environment (G x E) interaction structure and the influence of environments on additive, dominance and epistatic gene effects. Grain and malt characters, such as 1000-grain weight, percentage of plump kernels, malt extract yield, protein content, Kolbach index and malt fine-coarse difference were measured. The results show that additive effects had the greatest interaction with environments for all analysed traits, but only for malt characters this interaction was linear. The results suggest that effects of heterozygous loci are more stable in contrasting environments than effects of homozygous loci
