The collection of genetic sources of the world assortment of hop varieties contains 289 genotypes, 224 of them are of a foreign origin, they come from 23 countries. They have been cultivated and their characteristics evaluated in the field collection inside the Hop Research Institute, Ltd., Zatec. The possibility of their utilization as female partners for hybridization process is studied in dependence on hops yield and bitter acids content. Genotypes of the European origin (Perle, Spalter Select and Hallertau Tradicion) seem to be the most suitable for breeding process of aroma hops. Females of hop varieties Yeoman, Target, Hallertau Magnum, Galena and Chinook proved to be the most suitable ones for hybridization process of bitter hop varieties.
