Abstract
The article presents the results of breeding work for the creation of new high-yielding varieties of bitter-aromatic hops with a high content of alpha-acids carried out in 2004-2020 in the Chuvash Republic on gray forest soils. The work was done by individual clonal selection of the best hop plants from the collection nursery. Seven high-yielding breeding numbers with a high alpha-acid content were selected from the collection nursery. After passing through all the stages of study in each of the appropriate nurseries from seven numbers, two clones were selected to create new varieties. Data were obtained on the parameters of the initial clonal breeding material, depending on weather conditions and the age of plantings. The selected clones (1-17 bitter-aromatic type and 6-26 bitter type) correspond to the specified indicators: collection of raw hops is not less than 4.0 kg from a bush, the duration of the growing period is 100-120 days, the content of alpha acids is not less than 5.0 %. Documentation on clone 1-17 was sent to the State Variety Commission for registration of a new variety Salampi. The variety is characterized by stable performance and quality indicators. The productivity of the variety is 30.0 c/ha (4.0 kg/bush) with a content of alphaacids of 9.3 %. The Podvyazny standard variety has 26.4 c/ha (3.5 kg/bush), the content of alpha-acids is 8.8 %. Testing of clone 6-26 will be continued to obtain complete and objective data.
