Abstract: Wider use of barley with great food potential due to its high nutritional value of grain is constrained by lack of knowledge about the functionality of barley grain components in terms of processing and food products development. Selected genotypes of hulless spring barley (cv. AF Lucius, lines KM 2084, KM 2283, KM 1057 and genetic resource Nudimelanocrithon) were examined for chemical composition (crude protein, starch, β-glucans, macro-minerals) and breadmaking properties of grain and grain milling fractions (flour, semolina, bran). Differences in chemical composition of genotypes reflected in both the yield and rheological properties of individual milling fractions, measured with farinograph and extensograph. The addition of barley flour (15-30%) or barley semolina and bran (10 and 20%) to standard wheat flour reflected in different rheological properties depending on a barley genotype. The farinograph parameters largely varied in individual materials, however, the percentage of barley fractions in the mixture did not affect the values considerably. In comparison with standard wheat flour, values of extensograph parameters were low (especially for energy and extensibility) in all barley samples studied. However, they were affected by both the proportion of barley fraction and its interaction with a rest period. When the rest period was longer (90 min), even higher additions of semolina or bran (especially in cv. AF Lucius) were technologically acceptable.
