Cherry variety Ovstuzhenka

Ovstuzhenka is a sweet cherry variety with fruits of early middle ripening period. Bred at the All-Russian Research Institute of Lupine by hybridization of 2 varieties - Compact Venyaminova and Leningradskaya Black. The authorship is assigned to M.V. Kanshina.

Since 2001, the variety has been included in the State Register of Breeding Achievements in the Central Region (Bryansk, Vladimir, Ivanovsk, Kaluga, Moscow, Ryazan, Smolensk, Tula regions). It showed itself very well when grown in the south of the Non-Black Earth Region.

The trees are small and fast growing; crown of medium density, slightly raised, spherical in shape. Shoots of medium thickness, straight, not pubescent, colored brownish brown. Buds are large, pointed, vegetative - cone-shaped, strongly deflected, generative - ovoid, strongly pointed. Leaves are large, ovoid, with a sharply pointed tip and rounded base, along the edge - double-serrate serration, color - green, young leaves - pigmented. The lamina is flat, matte. The petioles are medium in thickness, short in length, each with 2 colored glands.

Inflorescences are three-flowered. The flowers themselves are large, the petals go one after the other. The corolla is saucer-shaped. The stigma of the pistil is at the level of the stamens or slightly higher; pistil and stamens are long. The calyx is cup-shaped, the sepals are not serrated, pigmented. Fruit ovary formation is concentrated on bouquet twigs (up to 63%).

Cherry fruits Ovstuzhenka are large (the average weight of a berry is 4.2 g, the largest specimens can grow up to 6 - 7 g; height - 1.9 cm, width - 1.9 cm, thickness - 1.6 cm), in shape - round / oval, dark red in color (almost black). The stalks are medium in length and thickness, the separation is dry. Seeds weighing up to 0.27 g (6.4% of the total weight of the berry), ovoid, with a pointed tip and wide-rounded base, color - light brown. The separability from the pulp is good. The fruits do not crack even in wet years.

The pulp is of medium density, colored, like the juice, in a dark red color, the taste of cherries is very good - juicy, sweet. Tasting score - 4.5 - 4.7 points. By chemical composition, berries contain: dry matter (17.2 - 17.7%), the amount of sugars (11.6%), acids (0.4 - 0.45%), vitamin C (13.4 mg / 100 d). The use of the variety is universal.

Flowering takes place early, fruit ripening at the end of June. Fruiting begins from the 4th - 5th year.

In general, the Ovstuzhenka sweet cherry is rated as high-yielding. Although the average productivity of young trees is not that high and is equal to 15 - 16 kg / fowl. (or 102 kg / ha), the maximum yield reaches 30 kg / der. (or 206 c / ha).

The winter hardiness of the variety is good. After severe winters, freezing of trees was 0.3 points, 34% of flower buds died. After the spring frosts, 19% of the pistils died. Also note the resistance of the stem and the base of the skeletal branches to frost breakers and sunburn.

The variety is highly resistant to fungal diseases - moniliosis and coccomycosis, resistance to clasterosporiosis is at an average level.

Self-pollination of this cherry is low (up to 5%). To increase the yield, it is recommended to plant additional pollinating varieties near it. The best among them: Bryansk pink, Iput, Raditsa, Jealous, Pink pearls, Tyutchevka.

The main advantages of Ovstuzhenka cherries are: attractive fruits with excellent taste, short trees, relatively early ripening, stable fruiting, disease resistance.

There were no significant shortcomings in the variety.
