KORINKA RUSSKAYA

Korinka Russkaya is a seedless table grape variety developed by breeders at the Central State Laboratory named after I.V. Michurin. This variety is characterized by a very early ripening period: the harvest begins at the end of July or early August, with full maturity achieved 105-115 days after bud swelling. The bushes are vigorous, reaching heights of 2-3 meters, possess good winter hardiness, and can comfortably withstand temperatures down to -25-28°C without covering. The flowers are bisexual, ensuring self-fertility and stable yield. The clusters of Korinka Russkaya are medium to small in size, conical in shape, often with wings, loose, and usually weigh no more than 250 grams. The berries are small, round, about 8-10 mm in diameter, golden-green in color with a pinkish tint on the sun-exposed side. The skin is of medium thickness and breaks easily, while the flesh is fleshy, juicy, and sweet with no pronounced aroma. The sugar content of the berries reaches 20-23%, and acidity ranges from 4-6 g/L, making the grapes pleasant to taste and suitable for fresh consumption, as well as for juice production and raisin drying. The variety exhibits good resistance to downy mildew and grey rot, but is susceptible to powdery mildew, which requires regular preventive care with the application of fungicides. The leaves are large, five-lobed, medium-depicted, and slightly wrinkled, with hair along the veins. Due to its characteristics and universal usage, Korinka Russkaya is a popular choice for growing in regions with a moderate climate, providing a stable and high-quality early grape harvest.
