  • sweet, not overloaded with additional notes taste;
  • consistently high yield ≈ 80 c / ha;
  • transportability;
  • consumer versatility;
  • berries do not shrink under any weather conditions;

The negative aspects 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, the palatability, the ripening time, the transportability of the crop, the plant's resistance to frost and disease.

Bush and leaves

The bushes of Korinka Russkaya are 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. The root system is branched, powerful.

Productivity 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 is medium friable, which contributes to better ripening - above 80%. The sugar content of the total mass fraction of juice is 20-22%, acid - 5 g / l.

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

Technical characteristics of the variety

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

Disease immunity

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

Frost resistance

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

In which areas can you grow

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

Growing in central Russia has one advantage - the berries left until fully ripe 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 upward, and not creep along the ground. It is recommended to plant grapes Korinka Russian 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.

Moistening the soil

The soil is moistened 4 times per season:

  1. before blooming leaves;
  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 of the vineyards stops 4-5 weeks before the harvest.

Mulching

Warming of the soil with sawdust, straw, hay, peat is done 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 insulating layer. It will create a greenhouse effect. In dry areas, mulching is also carried out in the summer to prevent moisture evaporation and protect the site from weeds.

Pruning

Top dressing

Organic matter for grape bushes is introduced in the fall in a period of 2-3 years. Mineral substances 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 bunches. To obtain a larger bunch, treatments with "Gibberellin" are carried out.

Protection against diseases and pests

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

Fruiting and harvesting period

From the opening of the buds to the ripening of the berries, 110-115 days pass. 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.
