The prospects of black currant selection for berries’ fruit quality under the conditions of the Bashkir Cis-Urals

The research objective was the creation and allocation of donors of high content of biologically active agents in blackcurrant berries. As the objects of the researches the varieties and perfect forms of currant of black selection of the Bashkir RDIA were used. The variety Valovaya served as the control. The frequency of the experiment was triple, in each frequency on 10 plants according to the scheme of planting 3 × 1 m. Biochemical analyses of berries were carried out by the standard techniques. During 2013-2017 biochemical structure was studied in 8 varieties and 20 perfect forms of currant of black local selection. In blackcurrant berries the sum of sugars on average value on all studied variety specimens was from 7.8 % in the variety Valovaya and to 10.4 % in specimen 3-49. At the control variety Valovaya it was equal to 7.8 % and practically all the varieties and forms surpassed the control variety in the content of sugars in berries. The samples with the highest content of A-1, A-2, A-3,3-49, 3-45, 5-11 sugars and the variety Belskaya which content of sugars exceeded 10 % were allocated...
