Chemical composition: soluble dry matter — 11.7-13.8%, total sugars — 9.2-10.8%, titratable acidity — 1.92.0%, ascorbic acid — 98.7-167.0 mg/100 g, P-active compounds — 167.0-360.0 mg/100 g, soluble pectin — 0.5%.
High-yielding variety, average yield 5.9 t/ha, maximum 9.7 t/ha at 4-6 years of age under planting scheme 3.0 x 1.5 m, self-fertile (44%). Best pollinators: Primorsky Champion, Selenга, Zabaykalochka, Gor-hon. High winter hardiness, medium resistance to powdery mildew and bud mite.
