The following spring barley malting varieties were registered in the Czech Republic in 2012: Explorer, Signum, Sunshine, and Zeppelin. The highest extract content was exhibited by the varieties Signum and Zeppellin (83.7 %). All four varieties had high level of proteolytic and amylolytic modification. The value of final apparent attenuation was high for the varieties Zeppelin, Explorer, and Sunshine (82.9- 83.8 %), low for the variety Signum (80.1 %). Modification of cellular walls moved ranged from 88 to 97%, which reflected low β-glucan content in sweet wort (43-144 mg/l). None of the varieties was recommended for production of beer with the protected geographical indication "České pivo/Czech Beer". Further, one non-malting two row barley variety (Wiebke) was registered. In autumn 2011, non-malting two-row barley varieties, Fabian and Sandra, and six-row winter barley varieties, Doreen, Henriette, KWS Tenor, Marissa, and Sylva, were registered.The following spring barley malting varieties were registered in the Czech Republic in 2012: Explorer, Signum, Sunshine, and Zeppelin.
