Chemical composition: dry solids — 7.8%, sugar sum — 5.6%, titratable acidity — 3.5%, ascorbic acid — 34.8 mg/100 g, P-active substances — 300.0 mg/100 g, pectin (on dry weight) — 5.1%.
Winter-hardy, high-yielding, average multi-year yield 4.5 kg/bush, self-fertile.
Advantages of the variety: winter hardiness, high yield, resistance to fungal diseases.
