Currant vigorous

A rare culture is so immune to disease and pest attacks, as well as the vagaries of the weather. In addition, Yadrenaya bears very large and delicious fruits. And growing it is a pleasure.

The culture was the result of the work of the Federal Altai Scientific Center of Agrobiotechnology (FGBNU) and, in particular, the employee of the institution L.N.

In the process of experimental testing, the newly-made culture demonstrated a decent level of frost and drought resistance, tolerated the effects of pathogenic microflora and pest attacks well. And its fruits amazed many with their significant dimensions and memorable taste. The variety has been in the State Register since 2000. It is intended for cultivation in the conditions of the West Siberian and Volga-Vyatka regions.

The bushes of this black currant are compact, medium-sized, slightly leafy, slightly spreading. Reaches a height of 150 cm. The crowns are not dense. Erect shoots of moderate thickness, medium size, greenish with a slight blush and little pubescence.

The foliage is dark green, five-lobed, wrinkled and bubbly. Veins of pinkish shades, slightly depressed into leaf plates. The edges of the leaves are sharp, with slightly curved teeth.

The flowers are small in size, white-pinkish, with a memorable sweetish aroma.

Of the advantages of culture, we note:

• high level of productivity and large-fruited;
• excellent winter hardiness and frost resistance (with satisfactory snow cover, tolerant to temperatures up to 40 ° C);
• able to endure long winter thaws without noticeable difficulties;
• has a high degree of heat resistance and drought resistance;
• tolerant to powdery mildew and hazel grouse virus;
• tolerant of kidney mites.

Minuses:

• contains an excessive amount of acid in berries;
• non-uniformity of fruits;
• low level of transportability;
• weakly resistant to anthracnose;
• rapid aging of plants;
• a small number of shoots after pruning.

The culture is quite simple in agricultural technology, it is often used for cultivation by amateur gardeners, as well as for commercial purposes. The fruits are mainly used for fresh consumption and for processing. We recommend them to connoisseurs of large fruits with an impressive currant aroma.

The berries are almost black, large in size (3.2-7.8 g), oval in shape, with shine. The skin is firm and fleshy. Brushes are elongated up to 8 cm. The number of fruits in a cluster is in the range of 6-12 pieces. The fruit contains many large, but soft seeds. Consistency is compacted, saturated. The separation of the fruits is dry. The level of transportability (in the phase of technical maturity) is good.

By chemical composition, the fruits include: sugars - 8.9%, acids - 3.7%, vitamin C - 96 mg /%.

By taste, the berries are sweet-sour, with a refreshing aroma. Tasting score in points - 4.3.

The culture is early-growing, medium-late ripening. Fruiting time July-August.

The plant is high-yielding - on average, up to 87.6 kg / ha, 2.5 kg per bush.

The culture is considered self-pollinated, but additional plantings of other types of currants are desirable to increase the yield level.

Landing sites for Yadrenaya should be sunny. In southern latitudes, it is better to plant bushes in a semi-shaded space. The bushes are planted in the fall, with a distance between them of at least 1.5-2 m, since a denser planting reduces the area of ​​their nutrition, which leads to shrinking of the berries.

Before planting, organic compounds are added to the soil both in the planting recesses and on the surface of the soil about 2 m in diameter, followed by digging. An hour before planting the seedlings, the roots are immersed in water so that they replenish their moisture reserves. With a closed root system, the bushes are immediately planted, followed by abundant irrigation.

When planting in spring, the bushes are shortened to 3 buds. Seedlings should be planted obliquely to create conditions for better shoot development, since the culture poorly develops roots.

It is recommended to irrigate every 7 days - 30-40 liters per bush. Although the culture is quite drought-resistant, in the absence of irrigation, especially on dry days, the fruits begin to visibly shrink, and the ripe ones crumble. In order to avoid drying out of the soil under the bushes, mulching is carried out. Also, mulch saves the roots from excessive heating, which has a positive effect on the productivity of plants.

Irrigation should be carried out along the perimeters of the crowns, but not in the center of the bushes, since there are no sucking roots there. During the period of fruit ripening, watering is reduced, since otherwise the berries begin to crack. Fruits ripen Vigorously synchronously, and they are removed during ripening. You should not overexpose them, otherwise the level of sugar content drops.

The best time for autumn pruning is the second decade of October. It should not be carried out later, since the tips of the branches may freeze slightly, and in the spring they will have to be cut out anyway.

In the 1st year of fruiting, only 2 shoots should be left. In the future, intensive pruning is carried out annually, since the culture is soon aging, and it gives few shoots. For this reason, starting from the 3rd year of fruiting, the row of branches should be shortened by about 30%. If such pruning is unsatisfactory, then 1-3 weak branches at the base are eliminated, then basal processes will begin to appear.

The culture throughout the entire fruiting period needs cardinal pruning, otherwise its productive period is reduced to 5-7 years. A fully formed bush should have 10-12 shoots.

The variety is sensitive to feeding. Traditionally, 2-3 additional dressings are carried out for him per season. During the periods of ovary formation, the bushes are sprayed with solutions of trace elements, including ash or other micronutrient fertilizers.Other supplements are not necessary during this time. We strongly discourage the use of nitrogen during fruiting.

During the rainy season, liquid root dressing is performed using similar solutions.

After harvesting the fruits, the culture must be fed with phosphorus additives, embedded in the ground, or irrigated with a phosphorus extract. At the same time, potash compounds are added (1 tablespoon per 10 liters of water). In the fall, additives from rotted manure or humus are added to the soil, embedding it into the soil to a depth of 5-7 cm.

The near-stem spaces are not digged, since the roots of the culture are located superficially - they can be damaged.

The variety has a strong immune potential against diseases and pest attacks, for this reason, preventive measures are taken in early spring, before flowering and in autumn. Affected and diseased branches are eliminated.

The culture was "born" in Siberia, and therefore is not afraid of harsh winters. But to reduce the risk in October, areas near the bushes with a diameter of 1 m are covered with humus, fallen leaves at least 5 cm thick. In winter, the bushes are covered with snow.
