Grapes Korinka Russian: description and characteristics of the variety, cultivation and care with photo

Recommendations for growing grapes Korinka Russkaya apply to areas of the Central Black Earth region. It is in the section for this part of the country that it can be found in the State Register of Fruit Trees. The variety is characterized by high rates of winter hardiness, resistance to diseases, early fruiting. A team of professional breeders worked on its breeding.

History of Breeding

Korinka Russian, stenospermocarp variety - seedless. It was bred by Lena Timofeevna Shtin and Ivan Maksimovich Fillipenko. This married couple, who worked in the CGL them.I. V. Michurin (in the Tambov region), authorship of 8 grape varieties, but only 4 of them are adapted for the Central Black Earth District. The grape variety Korinka Russkaya was based on the vine of the Dawn of the North and Kishmish Cherny.

Advantages and disadvantages of the species

From parental shoots, the variety took such advantages as:

• high rate of crop maturation;
• sweet taste, not overloaded with additional notes;
• stably high yield ≈ 80 c/ha;
• transportability;
• consumer versatility;
• berries do not shrink under any weather conditions;
• frost resistance.

The negative sides of the vineyard include the height of the bushes, which makes harvesting somewhat difficult.

External data

The description of grapes consists of several factors - the height of the shoots, the size of the berries, taste, ripening time, transportability of the crop, plant resistance to frost and disease.

Bush and leaves

Korinka Russkaya bushes differ in height that is not standard for grapes, they reach 3 m. The lower tier of the shrub is made up of shoots 2.1 m long. The vine is light brown in color. The root system is branched, powerful.

You can recognize this variety by large wrinkled leaves that do not have a deep dissection, the pubescence on them looks more like a rare cobweb.

The color is green, but the veins have a yellowish tinge. The bush is strong, strong, sprawling and self-fertile, during the flowering period bisexual flowers bloom on its shoots.

Yield and taste of berries

The yield of the Korinka Russian variety is stable, annual. On average, up to 800 kg of sweet berries can be harvested from each hectare. The average weight of a bunch is 250 g, its shape is conical, the structure of medium friability, which contributes to better ripening - above 80%. The content of sugars from the total mass fraction of juice is 20-22%, acids - 5 g / l.

Tasters recognized this proportion as the best. Consumers in this variety of berries like the thin skin, juicy, sweet flesh.

Technical characteristics of the variety

Korinka Russian refers to table varieties, but rounded berries are not large - from 8 to 10 mm in length, yellow color, the sides of the berries caressed by the sun's rays acquire a pinkish blush.

Immunity to diseases

When grown in the Central Black Earth region, the variety has high immunity to common grape diseases.With proper care, the absence of waterlogging of the soil and in other regions, this variety can be protected from all types of diseases by preventive treatments of bushes and soil. When growing Korinka Russkaya in cold areas, the main pathogens of grape diseases die in severe frosts.

Frost resistance

In regions where the air temperature drop does not exceed 26-28 °C, Korinka Russkaya winters comfortably. In areas with a more severe climate, this grape variety is grown as a covering crop.

Which areas can be grown

The middle zone of Russia, the B altic States and other regions of temperate continental climate are suitable for growing Korinka Russkaya grapes in open ground. The only feature is the additional warming of plants in preparation for the winter period. In the North-West region, the harvest will take place at the beginning of September, which is almost a month and a half later than this period will come in the Krasnodar Territory.

Growing in central Russia has one advantage - the berries left to fully ripen on the bushes acquire a honey flavor and aroma.

Features of agricultural technology

The vine resembles a bindweed, which needs support in order to strive upwards, and not to creep along the ground. It is recommended to plant Korinka Russian grapes in a trellis. This will not only decorate the site, but also give access to the sun's rays to more berries. The quality and weight of the crop will only get better.

Soil moistening

The soil is moistened 4 times per season:

1. before the leaves open;
2. at the initial stage of flowering;
3. during the formation and swelling of berries;
4. before the onset of frost, the soil is moistened for the last time.

Attention! Watering stops 4-5 weeks before harvest.

Mulching

Soil warming with sawdust, straw, hay, peat is carried out after water-charging irrigation, which simplifies the wintering of the plant. First, it is necessary to remove fallen leaves from the site, in which the pathogen can overwinter, and cover the area adjacent to the bush with a 10-centimeter warming layer. It will create a greenhouse effect. In dry areas, mulching is also carried out in the summer to prevent evaporation of moisture and protect the site from weeds.

Cutting

Planned autumn pruning is to plan next year's harvest. Each vine should not have more than 10 eyes. The bush is able to provide nutrients to 40 buds. Adjustments are made in the spring, leaving only one bunch of grapes per vine.

Feeding

Organics for grape bushes are brought in from autumn in a period of 2-3 years. Minerals are introduced into the soil in the spring before flowering, at the time of the formation of ovaries, at the stage of intensive growth of clusters. To obtain a larger bunch, Gibberellin treatments are carried out.

Protection from diseases and pests

Prevention, timely removal and burning of affected leaves and shoots, spraying with Bordeaux mixture, cleaning of fallen leaves, mulching and drainage of the site, application of mineral root and foliar dressings - the best protection of the plant from insect pests, fungal infections.

Fruiting and harvesting period

It takes 110-115 days from the opening of the kidneys to the ripening of the berries. In the southern regions, on the eastern slopes open to the sun, the berries are ready for use in the last decade of July.In the open ground of the Moscow region and the Leningrad region, you can taste ripe berries only in late August - early September.

Where to use grapes

The quality and taste of Russian Korinka berries are similar to kishmish, respectively, they are great for fresh and dried use. Compotes can be prepared from grapes and fresh berries.
