The effect of variety, cultivation locality, year and intensity of cultivation on the grain yield and selected parameters of technological quality was studied in winter wheat. Experiments were conducted with eight varieties cultivated during three years on four experimental sites at two intensities of cultivation - basic and increased. Viscoelastic properties of gluten, starch and ash concentrations, falling number, amylographic maximum and yield of flours were influenced especially by the genotype, while the locality influenced mainly crude protein and wet gluten concentrations. Bulk density was affected by the year, whereas grain yield was influenced by cultivation intensity and locality. Correlation analysis showed a lot of statistically significant positive as well as negative relationships.
