The study presents malting quality and agronomic characteristics obtained during testing of barley varieties in the Czech Republic. After the harvest of 2020, the following spring barley malting varieties were registered: Amidala, Focus, Greenway, KWS Jessie, LG Belcanto, and LG Stamgast. LG Stamgast was recommended for production of the beer with the protected geographical indication České pivo. In addition, the non-malting spring barley variety RGT Gagarin was registered. Amidala, Focus, Greenway, KWS Jessie, LG Belcanto provided malt with the extract content over 83%. These varieties also easily degraded nitrogenous substances. The value of the Kolbach index ranged from 48.6 to 52.1%. Diastatic power was at the optimal level. Degradation of cell walls was also optimal. Friability moved from 89 to 97% and β-glucan content in wort achieved satisfactory values of 65 – 170 mg/l in the given varieties . Wort quality, which is characterized by final attenuation, was at the above average to optimal level of 80.9 – 83.2% in these varieties of spring barley. LG Stamgast showed lower values of proteolytic and cytolytic modification and lower values of final attenuation, which is required for the varieties recommended for the production of the beer with the protected geographical indication České pivo.
