In 2011 following spring barley malting varieties were registered in the Czech Republic: Concerto, Monalisa, Jazz, Delphi, and Despina. The highest extract content was found in the variety Concerto (83.6 %). The varieties Monalisa, Concerto, and Despina exhibited a high level of proteolytic modification. Proteolytic modification in the varieties Jazz and Delphi was on the optimal level. Amylolytic modification and quality of wort given by the value of apparent final attenuation were in all the studied varieties on the optimal level. Modification of cell walls was given by the value of friability and ranged from 83-94 %. The varieties Delphi and Monalisa had a higher β-glucan content in wort (218-225 mg/l). None of the given varieties was recommended for production of beer with the protected geographical indication "České pivo". Further, five winter barley non-malting varieties were registered: two row Casanova and six-row varieties Nero, KWS Meridian, Lester, and Tatra.In 2011 following spring barley malting varieties were registered in the Czech Republic: Concerto, Monalisa, Jazz, Delphi, and Despina.
