Late-maturing variety, developed at the Mountain Horticulture Department of the Siberian Institute of Horticulture named after M.A. Lisavenko, by crossing the variety 'Pлотноки-стная' with seedlings from open pollination of a selected form of the Siberian subspecies from the river Ilyumen'. Author: L.N. Zabelina. Under state variety testing since 2000.
Plant is tall, upright, medium density. Growing shoots are thick and medium thickness, green with a pinkish blush; woody shoots are thick, light-brown, weakly shiny. Buds are medium-sized, oval-rounded, single, clustered and deviated at the top of the shoot, light green with a pinkish blush.
Leaves are three-lobed, large, bright green, dense, smooth, without hairs. Lobes are pointed, central lobe is broad. Angle between central veins of side lobes is straight. Basal lobes are weakly developed. Leaf base is deep, cleft, closed in young leaflets. Teeth are small, rounded. Leaf petioles are thick, medium length and short, hairy, light green, positioned at an acute angle (45-90°) to the shoot.
Flowers are medium-sized, sepals creamy with pink margins, petals creamy and not fused, deviated. Cymes are long (8-12 berries), dense, single per node, medium thickness, green, weakly hairy. Pedicels are short, medium thickness, weakly hairy.
Berries are large and very large (1.6-3.6 g), round, one-sided, black, weakly shiny, with a slight bloom, dry detachment, with many small, light-brown seeds. Calyx is medium-sized, falling off. Skin is thin, elastic. Taste is dessert. Chemical composition of berries: dry substances - 18.4%, total sugars - 8.7%, titratable acidity - 2.2%, ascorbic acid - 177 mg/100 g.
Cold-hardy variety, high-yielding (11.1 t/ha), self-fertile, resistant to anthracnose and septoria.
Advantages of the variety: high stable yield, tolerance to soil mechanical composition and fertility, high winter hardiness of generative buds and flower resistance to spring frosts, dessert taste and berry technology.
Disadvantages of the variety: insufficient resistance to bud mite.
