During 2009-2011, the spring barley malting varieties IS Carmenta, IS Castor, Despina, SU Flipper, Jazz, Laudis, Signum, and Zhana were assessed in the CCTIA Bratislava and RIBM Brno. Malting quality of all the varieties studied got near the standard varieties Nitran and Xanadu. Nearly all the studied varieties had extract content higher or at the comparable level as the standard variety Nitran, and four varieties exceeded also the standard variety Xanadu with the value of extract 83.6 %. The values of amylolytic and cytolytic modification were in new varieties at a good to optimal levels. The level of proteolytic modification was also higher. The highest level of attenuation was found in the variety SU Flipper (83.2 %). β-Glucan content in wort ranged from 76 mg/l (Despina) to 222 mg/l (Zhana). At the end of 2011, two winter barley non-malting varieties were registered: the two-row variety Korbina and six-row variety Patina.During 2009-2011, the spring barley malting varieties IS Carmenta, IS Castor, Despina, SU Flipper, Jazz, Laudis, Signum, and Zhana were assessed in the CCTIA Bratislava and RIBM Brno.
