Spring barley malting varieties Accordine, KWS Fantex, LG Nabuco, Pilote, and Spitfire and winter barley variety KWS Donau were registered after harvest 2017. The spring barley varieties were rich in extract. The varieties Spitfire, LG Nabuco, Accordine, and KWS Fantex had more than 83% of extract. Proteolytic, amylolytic and cytolytic modification was optimum in most studied varieties of spring barley. The variety Spitfire was characterized with a strong proteolytic modification (Kolbach index 51.1%). The variety KWS Donau had extract content at the level of 81.4% and a low level of proteolytic and cytolytic modification. Wort quality (apparent final attenuation) was in all the studied varieties at an above average to optimal level. In addition, non-malting varieties of spring barley Bente and winter six-row varieties KWS Belissa, Higgins, LG Triumph, Novira, and SU Ellen were also registered.
