Breeding Process Aimed at Dwarf Hops

Abstract

Crossings aimed at breeding of new dwarf hop progenies were carried out within the international EUREKA project. Totally 22,327 genotypes were obtained. After the assessment lasting for four years twelve perspective genotypes entered the registration trials in Central Institute for Supervising and Testing in Agriculture. The most effi cient are genotypes N11 and N12 with alpha bitter acids contents of 8.85, resp. 7.71% and yield of 1.75 t/ha, resp. 1.3 t/ha. Genotypes N5 and N10 are very similar from alpha bitter acids contents and composition of hop resins point of view to Saazer. Genotype N6 is interesting because of the mixture of fl oral, fruity and spicy aromas of its cones. At present all these genotypes are tested not only by farmers but by brewers as well.
