The tests were conducted on flour from grain of 3 cultivars of winter wheat (‘Izolda’, ‘Korweta’, ‘Roma’) and 4 spring cultivars (‘Hena’, ‘Torka’, ‘Santa’, ‘Jasna’) coming from two years of harvest, and on barley flour from laboratory grinding. The total amount of proteins, quantity and quality of wet gluten, sedimentation number and drop (precipitation) number were described in the flour. In wheat-barley blends a farinographic evaluation was performed together with laboratory baking. It was stated that a 5% addition of barley flour to wheat flour caused an increase in water absorbency of flour from all evaluated wheat cultivars. Replacement of wheat flour with barley flour had a diverse influence on rheologic features of dough produced from flour particular cultivars. Volume of wheat-barley bread was generally larger than comparing to volume of wheat bread.
