Quality of wheat grain is a complex trait that depends mostly on the quantity and quality of protein and unified interactions between high molecular glutenin, gliadin, low molecular glutenins and abiotic stresses. The objective of this study was to evaluate the effects of genotype, environment and genotype × environment interaction on quality and some agronomic traits in wheat. Twenty divergent genotypes of winter wheat, per five from Serbia, Russia, France and Hungary were analysed in this paper. Variability was observed for quality (grain protein content and sedimentation) and agronomic traits (thousand-grain weight and test weight) in three growing seasons (2007/08, 2008/09 and 2009/10). Genotypes were statistically analysed [basic statistical parameters, AMMI biplot for the content of protein, correlation and Principal Component Analysis (PCA)] in order to assess the impact of different growing seasons on selected cultivars. AMMI analysis determined that 2008/09 was very significant for most of the genotypes. The Hungarian cultivar GK-Zugoly had the highest grain protein content (14.4%). Correlation analysis showed different relationships between the traits. PCA indicated that the total variation reflected the first two components represented with 80%, but the first principal component was more important. Results of this paper indicate that the varieties MV-Csardas and Pamyati Kalinenko can be used as a good source of genetic material for future breeding program for agro-ecological conditions of Vojvodina.
