In 2015, following spring barley malting varieties were registered in the Czech Republic: Gesine, Kampa, KWS Amadora, Prunella, and Sanette and a winter barley variety KWS Ariane. The varieties KWS Amadora (81.6%) and Sanette (83.2%) had the highest malt extract. Except for the variety Kampa, all studied varieties showed an average to optimum level of proteolytic modification. The values of diastatic power moved from 271 to 420 WK un. Except for the variety Kampa, final attenuation moved from 81.8 to 83.1 % in all varieties. Degradation of cell walls was optimum in all studied varieties (81 to 97%). Increased β-glucan content was found only in the variety Kampa (239 mg/l). In all studied varieties, the β-glucan content moved from 55 – 182 mg/l. Due to a lower level of proteolytic modification and lower level of final attenuation, the variety Kampa was recommended for production of beer with the Protected Geographical Indication “České pivo/Czech Beer”. In addition, spring barley non-malting varieties, Kvorning and Solist, and winter barley non-malting two-row varieties, KWS Glacier and Padura, and six-row varieties Tamina, Johanna, Conny and a hybrid variety Wootan were registered.
