Barley varieties registered in the Slovak Republic in 2015

Abstract

The spring barley malting varieties Exalis, Montoya, Odyssey, Olympic, and Overture were registered after three-year tests (2012–2014). The highest extract content was found in the varieties Overture, Odyssey, and Olympic (83.9 %, 83.1 %, and 83.1 %, respectively). All the studied varieties exhibited a very good to optimal level of proteolytic and amylolytic modification. The highest values of apparent final attenuation were recorded in the variety Overture (82.7%). The level of cell wall destruction given by friability was optimal in all the studied varieties (87–93 %). beta-glucan content in sweet wort varied in the range of 115–186 mg/l. The varieties under study did not have problems with wort clarity.
