Original language description

PATZAK, Josef and Alena HENYCHOVÁ. Utilization of an enlarged set of molecular markers for control of authenticity and an evaluation of genetic variability within actual hop cultivars. In: F. WEIHRAUCH, ed. Proceedings of the Scientific-Technical Commission 25 – 29 June 2017, St. Stefan am Walde, Austria. Wolnzach: Scientific-Technical Commission of the International Hop Growers´ Convention, 2017, pp. 87–91. ISSN 2512-3785. Traditional hop cultivars have been used in brewing industry for a long time. About ten new breeding lines were realized for the world-wide market in every decade from the 1970s onwards. In the last decade, it was six times more, why it is necessary to control their genotype and origin. A utilization of DNA molecular genetic methods is the best solution for this purpose. We developed the efficient marker system for authenticity control of hop genotypes based on EST-SSR. The set of 11 loci effectively differentiated all used cultivars, breeding lines and wild hops, except for originally same genotypes of Saaz- and Fugglederived cultivars. We evaluated molecular genetic variability within 238 hop genotypes by 333 amplified molecular markers. Molecular genetic variability analyses corresponded with genealogical and geographical origin of individual cultivars, incorporated breeding events and influences of key cultivars.
