Barley varieties registered in the Slovak Republic after the harvest 2022

Abstract

The study presents the results of technological quality and agronomic characteristics of the spring barley LG Flamenco and winter barley Sonja. These varieties have passed three-year trials within the state varietal trials of the Slovak Republic. At the optimum nitrogen content in unmalted grain, the LG Flamenco variety showed an extract content of 83.2% and the Sonja variety 81.4%. The diastatic power was at the optimum level for both varieties (316 and 411 WK un.). The Kolbach index was at the optimum level (48.3%) for LG Flamenco and 39.6% for Sonja. In the LG Flamenco variety, cell wall degradation was given by a friability value of 88% and a β-glucan content of 192 mg/l. The friability value for the variety Sonja was 82% and the β-glucan content was 193 mg/l. The quality (apparent final attenuation) of the sweet wort was satisfactory for both varieties (81.0%).
