Variety Korinka

Korinka (Korinka Russkaya, “Russian Corinth”) is a seedless kishmish variety from the Michurin Central Genetic Laboratory (I. M. Filippenko and L. T. Shtin; Zoria Pivnochi × Kishmish Chornyi). It ripens very early: the berries begin to ripen in July–August. The cluster is small, 180–250 g, conical, often with a wing, loose. The berries are small, about 8 × 10 mm and up to 2 g, round, golden-yellow, with a pink tint on the sunny side; seedless. The flesh is fleshy and juicy, the taste harmonious, distinctly grapey; sugar content 20–22% and higher at acidity of 4–5 g/l. The skin is of medium thickness. The berries are eaten fresh and dried into raisins.

The bush is vigorous, the vine ripens well, yields are good. Frost resistance down to −25…−26 °C; cover is needed mostly in snowless and very cold winters. The variety is resistant to downy mildew (about 3 points) and susceptible to powdery mildew, so preventive treatments are needed.
