Barley Varieties Registered N The Slovak Republic After The Harvest Of 2020

The study presents results of malting quality and agronomic characteristics of the LG Verdi, LG Tosca, and Spitfire spring barley varieties that were obtained during a three-year period of testing within the state varietal trials in the Slovak Republic. Extract from the varieties was at the level from 82.9 to 84.1%. The varieties exhibited optimal and high levels of proteolytic modification (47.4 to 52.0%) and satisfactory to optimal levels of final attenuation (80.8 to 81.8%). Degradation of cell walls was high - between 86 and 96%. Beta-glucan content was at a satisfactory to optimal level of 67 to 158 mg/I. In addition, the study presents results which the Suez winter barley variety achieved in a two-year period of state varietal trials. The variety exhibited satisfactory quality of the extract level, optimal level of proteolytic modification and optimal wort composition. This variety had a slow degradation of cell walls, but its beta-glucan content was at the satisfactory level.
