Comprehensive assessment of red currant varieties in Altai

Abstract

Red currant (Ribes rubrum L.) is a berry crop promising for cultivation in Siberia. The purpose of the work was to study the elements of productivity and biochemical composition of fruits in 17 varieties of R. rubrum of various origins of the VNIISPK breeding. This article presents the results of the study of red currant varieties selected by VNIISPK in the Altai. Most varieties are highly resistant to gall aphids, with the exception of ‘Valentinovka’, ‘Orlovskaya Zvezda’ and ‘Orlovchanka’ - in some years, their damage was noted to a very weak degree. As sources of valuable biochemistry, the following varieties were identified: with a high content of soluble dry substances - Asya, Bayana, Vika, Dar Orla, Marmeladnitsa, Osipovskaya; sugar - Asya, Bayana, Roza; vitamin C - Asora, Asya, Protein, Vika, Marmeladnitsa, sugar-acid index - Asora, Orlovchanka, Roza. The varieties Asora, Asya, Bayana, Valentinovka, Vika, Dana, Dar Orla, Marmeladnitsa, Orlovskaya Zvezda, Orlovchanka, Osipovskaya, and Roza were identified according to the complex of economically useful traits (yield, large-fruited, biochemical composition, resistance to harmful organisms), which can be recommended for cultivation in the conditions of the Altai Ob region.
