Abstract

The guelder-rose(Viburnum opulusL.)has fruits rich in biologically active substances. The introduction of Vibur-num opulusL.into the garden culture as a fruit plant for the first time in our country was started in Barnaul at the Altai Zonal Fruit and Berry Experimental Station. The reason for the lack of commercially significant guelder-rose planta-tions in Russia is the unrevealed potential of the crop, the lack of varieties having a complex of technologically attrac-tive characteristics: compact crown of the bush, suitability for mechanized harvesting, early fruiting, high yield, low bitter tasting fruits that are suitable for fresh consumption in addition to processability. This paper describes the select-ed forms of Viburnum opulusL.developed at the Research Institute of Gardening in Siberia named after M.A. Lisaven-koof the Federal Altai Scientific Center of Agro-Biotechnologies, the City of Barnaul. The results of breed-ing work with Viburnum opulusL.revealed real opportuni-ties for developing varieties with a complex of high eco-nomically significant indices. The research goal was to study the hybrid of Viburnum opulusL.and to identify the selected forms with a complex of economically valuable characters. The results from 2013 through 2019 are dis-cussed. The research targets were 9 selected forms from 5 families. The research was carried out in the breeding gar-den planted in 2008. Throughout the observation period, the weather conditions in 2013 and 2015 were the most favorable for the growth and fruiting of Viburnum opulusL.From 2017 through 2019, there was no harvest due to se-vere damage to the plants by Pyrrhalta vibumi larvae and beetles. The seedlings were evaluated regarding the ma-turity period, fruit quality (size, taste), and yield. The gen-eral condition of the plants, disease damage and pest damage were also evaluated. The observations were car-ried out according to the generally accepted program and method of selection and variety study of fruit, berry and nut crops. According to the research findings, the forms 5-12-08, 5-6-08 and 8-29-08 were selected for high yields (four-year average -3.7 kg per bush; maximum -5.0 kg bush) and large-fruits (1.2-1.5 g). A good taste of fresh fruits (4.5 points) and a processed product -strained fruits with sugar (4.7 points) was noted in the hybrid 5-2-08. Regarding the total content of biologically active substances in the fruits, the selected form 6-8-08 was identified.
