Belskaya – a new variety of black currant

Abstract

The climatic conditions of the Republic of Bashkortostan require the creation of varieties with high resistance to a complex of biotic and abiotic stressors of the region of cultivation. The data on economically valuable characteristics of a new variety of black currant Belskaya (breeding number 4-46) are presented. The black currant variety Belskaya was bred in the Republic of Bashkortostan in 1997 from pollination of the Valovaya (Krupnaya × Bredtorp × Khludovskaya) and Karaidel (Pamyati Michurina × Compactnaya). The year of sowing is 1998, the beginning of fruiting is 2002, the selection of an elite seedling is 2003, the transfer to the state varietal testing is 2013. The primary study of varietal samples was started in 2005 according to the planting scheme of 3 × 1 m. The control variety was Valovaya which is widespread and zoned across all regions of the Russian Federation. The Belskaya variety is characterized by high winter hardiness. There were no signs of freezing in severe winters, in the control variety Valovaya damage was noted up to 1 point with freezing of the tops of the annual growth. The leaf apparatus of the variety is resistant to sunburns. During the hot and dry summers (2010, 2011), it was distinguished by high drought resistance, while its productivity was higher than the control variety. The new variety is characterized by high productivity (yield on average 12.7 t / ha), and is resistant to shedding. It has fi resistance to American powdery mildew, weakly affected by anthracnose. Berries are one-dimensional, black, round‒oval shape, weighing 2.3 g (maximum 2.6 g), sweet and sour delicate taste. The maturation period is average. In 2022, the Belskaya variety was included in the State Register of Breeding Achievements of the Russian Federation in the Ural region.
