In 2014, following malting varieties of spring barley were registered in the Czech Republic: Britney, Francin, KWS Asta, KWS Irina, Montoya, Odyssey, Overture, RGT Otakar, and SU Zaza. The highest extract content was found in the varieties KWS Asta and Overture (83.9 %). All the studied varieties exhibited a very good to optimum level of proteolytic and amylolytic modification. The highest value of the apparent final attenuation was found in the varieties KWS Irina (82.6%) and Overture (83.1%). Despite very good to optimal modification of cell walls (86-94 %), the varieties SU Zaza (237 mg/l), KWS Asta (213 mg/l) exhibited increased content of ß-glucans in wort. The variety Francin was mainly due to a lower level of proteolytic modification and lower level of apparent final attenuation recommended for the production of beer with the protected geographical indication "České pivo" (Czech Beer).In 2014, following malting varieties of spring barley were registered in the Czech Republic: Britney, Francin, KWS Asta, KWS Irina, Montoya, Odyssey, Overture, RGT Otakar, and SU Zaza.
