In 2009 following malting varieties of spring barley were registered in the Czech Republic: Advent, Henley, Henrike, Signora, Streif, and Vista. The winter barley malting variety Wintmalt was also registered. Content of nitrogenous substances moved from 10.4-11.3%. Extract content lower than 82.0% was determined only in the varieties Vista (81.6%) and Wintmalt (81.8%). Only the variety Henrike had high level of proteolytic modification. Proteolytic modification in the other varieties was very good to optimal. Amylolytic and cytolytic modification in all varieties was on the optimal level. Higher β-glucan content was only in the varieties Advent (301 mg/l) and Streif (253 mg/l). The variety Advent was recommended by the RIBM for the production of Czech Beer. The variety Wintmalt enlarged the possibility to acquire a quality malting material for winter barley. In addition, nonmalting spring barley variety Kontiki and nonmalting variety of hulless spring barley AF Lucius were registered. In 2009 four nonmalting varieties of winter barley, two-rowed variety Faraon and three six-rowed varieties Heike, Saffron, and Wendy were registered.In 2009 following malting varieties of spring barley were registered in the Czech Republic: Advent, Henley, Henrike, Signora, Streif, and Vista.
