Genotype by Environment Interactions in Wheat Quality Breeding Programs in Southeast Europe
The objective of this study was to determine genotype x environment interactions (GEI) obtained in wheat production in southeast Europe for protein content, sedimentation value and loaf volume. Twenty wheat genotypes divided in two groups with different combinations of high molecular weight glutenin subunits (HMWSB) were analyzed in 15 environments (E). In a combined analysis of variance, effects of genotype, environment and their interaction (GEI) were highly significant for almost all analyzed traits. All three traits were more influenced by location than by year, with protein content and sedimentation value being more responsive to changes in environmental conditions than loaf volume. The genotypes with high protein content had the regression coefficient value (b) close to 1, which indicated that they did not react to extreme environmental conditions as was the case with genotypes with high sedimentation and loaf volume values. There were no significant differences in average values for analyzed traits and adaptability parameters between the two groups of genotypes. It means that, concerning wheat quality improvement, genotypes with different HMW-GSs on the Glu-1D locus could be recommended for growing in southeast Europe. It is necessary to take in account the differences in adaptability of protein content to either positive or negative environmental changes that were observed between the groups.
