This study presents the results of malting quality and agronomic characters obtained within state varietal testsof malting barley in the Slovak Republic. After the harvest of 2019, new spring malting barley varieties of Avus,Bernet, and LG Nabuco were registered. The spring barley varieties provided malt with extract content above 83%. All varieties degraded nitrogenous substances easily. The values of Kolbach index ranged from 47.5 to 49.5%. Diastatic power was at the optimal level and moved above the level of 300 WK un. in all the studied varieties. Also, cell wall degradation was optimal and friability was higher than 90%. Content of β-glucans in wort reached favourable values (72–141 mg/l). Quality of wort characterized by apparent final attenuation was at the above average value to the optimal level (81–81.8%) in the studied spring barley varieties.
