Abstract
Red currant is a valuable berry crop. The assortment is improved through the selection of new varieties. In the Russian Research Institute of Fruit Crop Breeding (Russia), breeding work for red currant has been carried out since 1984. The ‘Heinemanns Rote Spatlese’ variety, selected in Germany in 1942 by crossing the Prince Albert variety with Andenken an Lorgus (type of multiflowered currant - Ribes multiflorum Kit. ex Schult.), was widely used as the initial form in crosses. The greatest breeding value was shown by the family 'Rote Spatlese'×'Jonkheer van Tets’, from which 7 varieties of red currant were obtained: Asora, Valentinovka, Dana, Dar Orla, Ogonyok, Orlovchanka, Podarok Leta. The combinations in which 2 varieties were selected were also effective: 'Rote Spatlese‘×'Red Lake' - Bayana (white-fruited), Selyanochka; 'Rote Spatlese'×'Minnesota’ – Osipovskaya, Orlovskaya Zvezda; 'Rote Spatlese'×'Maarse's Prominent' - Marmeladnitsa, Ustina. The research results show that the cultivar ‘Rote Spatlese ' is a valuable initial form in red currant selection for late ripening, long-raceme, high productivity. Based on the ‘Rote Spatlese’ genotype, VNIISPK has created 13 late-maturing, high-yielding varieties of red currant, 9 of them are included in the State Register of Breeding Achievements approved for use in the Russian Federation.
Highlights
Red currant is a berry plant of temperate climate, which has nutritional value and therapeutic effect [1,2]
In 1974, the VNIISPK for the first time created a collection of red currant varieties, including 22 varieties
One of the varieties accepted for the experiment was ‘Rote Spatlese‘
Summary
Red currant is a berry plant of temperate climate, which has nutritional value and therapeutic effect [1,2]. The interest in red currant has increased among Russian producers and processors of berry products. In increasing the cultivation profitability of any agricultural crop, including currants, the main role is played by the variety. Modern varieties of red currant should have high stable yield, resistance to pathogens harmful to the crop, wide response rate to environmental stress factors, be suitable for mechanized harvesting or produce high-quality berries for fresh products market [3, 4, 5]. The crop assortment is improved through the selection of new varieties. To speed up and improve the selection efficiency, it is necessary to have genetic collections of sources and donors of important economic and biological traits for the culture. The selection effectiveness largely depends on the choice of the initial forms
