Original language description

NESVADBA, Vladimír, Jitka CHARVÁTOVÁ and Sabina TRNKOVÁ. Czech bitter varieties of hops. In: F. WEIHRAUCH, ed. Proceedings of the Scientific-Technical Commission 25–29 June 2023, Ljubljana, Slovenia. Wolnzach: Scientific-Technical Commission of the International Hop Growers' Convention, 2023, p. 130. ISSN 2512-3785. In the years 2011 to 2022, the Czech hop varieties Agnus, Rubín, Vital, Gaia and Boomerang were evaluated in terms of their hop yield. The highest hop yield was recorded in Gaia (2.99 kg/plant) and Vital (2.92 kg/plant). Boomerang had the lowest yield (2.11 kg/plant.). The lowest variability of yield was determined in Vital (19.74%) and the highest in Boomerang (33.29%) and Agnus (32.98%). Vital demonstrated the lowest decreasing trend of hop yield over a period of 12 years. Rubin showed the highest decreasing trend. Hop varieties have an average content of alpha acids between 10.24 % w/w (Agnus) and 13.73 % w/w (Gaia). As to variability, all bittering hops have a good stability of alpha content because variability is below 15%.
