Winter variety obtained at the State Research Institute of Fruit and Vegetable Crops and the I.V. Michurin Institute of Plant Breeding, by S.P. Yakovlev, A.P. Grigbanov, N.I. Savelyev, V.V. Chivilev, through crossing the varieties 'Daughter of Dawn' and 'Late MOSVIR'. Approved for the Central Chernozem region since 2002.

Fruits medium to above medium size, weighing 140-220 g, pear-shaped, regular shape, smooth. Skin medium, oily, with waxy coating. Color at harvest: main green, covering pink on the lower part of the fruit; at consumer maturity, main green-yellow, covering brownish-red on the lower part of the fruit.

Fruits contain sugars — 9.2%, titratable acids — 0.05%, ascorbic acid — 13.2 mg/100g, P-active substances — 126.0 mg/100g.

Begins fruiting at age 5-6. High yield. Harvest maturity occurs in the second decade of September; consumer storage period in refrigerated storage is 220-250 days.

Characterized by relatively high winter hardiness. After artificial freezing in mid-winter at -38°C, bark showed no freezing damage; tissue damage to cambium and xylem did not exceed 1.2 points. Not affected by fungal diseases.

Advantages of the variety: compact crown, prolonged fruit consumption period, comprehensive disease resistance.

Disadvantages of the variety: slight astringency and small granulation in fruits.
