The best varieties of currant dobrynya

Black currant is one of the favorite berries of many gardeners. It is considered a fairly young culture, but there are more than two hundred varieties. Breeding continues, and almost every year a new species appears. We offer you to get acquainted with the currant "dobrynya". Description of the variety, features of care will be presented in the content of this article.

Withdrawal

The variety was obtained by the breeder A.I. Astakhanov is considered one of his most successful achievements. At the All-Union Research Institute of Lupina, the varieties "raisin" and 42-7 were crossed, so the currant "dobrynya" turned out.

In 2004, its cultivation began in the Central and West Siberian regions. The variety is ideal for the Middle Lane, it is also recommended for cultivation in many southern regions.

Description of the plant

Dobrynya currant bush is rather compact, moderately spreading, erect. Plants can be medium or short, depending on the growing area and soil quality. Young shoots are slightly drooping, not thick, but strong, have a beautiful olive-violet bark shade, shine a little.

The leaves have five lobes, leathery, dark green, wrinkled. Their size is from medium to large, the plate is even. Blades with small cuts, teeth not too long.

The brushes are slightly loose and sinuous, green in color. Each can have from 6 to 10 yellow, huge flowers. At the base, fruits appear quite rarely, most grows in the middle of the bush and at its top.

Characteristics of berries

Currant "dobrynya", the description of which you see, does not bear such a "name" for nothing. Its berries are very large, the average weight of one is about 6.5 grams. The shape of the fruit is slightly oval, the color is black, shiny. The variety is characterized by a rather dense peel, it prevents cracking of the berries, the separation is dry. Ripening occurs from late July to late August.

The berries are endowed with a delicate, attractive aroma, their taste is sweet with a characteristic sourness. Tasting score - 4.6. The pulp is juicy, the stalk is medium-sized, green. The sugar content is not less than 6.5 percent. Vitamin C - approximately 200 milligrams per 100 grams of berries.

Dobrynya currants are of medium yielding, on average 1.5 kilograms of berries can be harvested from one bush, which makes it less productive compared to other varieties. The maximum recorded yield is 2.6 kilograms per bush, or 12 tons per hectare.

Advantages of the variety

Dobrynya currant is a frost-resistant plant, bushes can survive winter frosts down to -25 degrees. If there are lower temperatures in the growing region, it is necessary to cover the bushes with insulating material and throw more snow on top during the winter.

The currant survives spring frosts well, does not shed flowers. If the summer is sultry and dry, then the bush will endure it steadily, you just have to follow the watering rules.

"Dobrynya" is considered a variety resistant to many diseases. It is rarely exposed to powdery mildew, but is susceptible to kidney mites.

Disadvantages of currants

There are also not very good characteristics in the variety. The first is a low yield compared to other types of black currant.The berries do not ripen synchronously, you will have to harvest in several stages. Transportability is low, like other similar berries. The fruits are caked, crumpled, thereby losing their presentation.

Also, the disadvantages include the poor survival rate of young cuttings. The root system forms slowly and may wither away. It happens that early opened buds wither in the middle of spring. It is recommended to use a root growth stimulator when planting, this will help the plant to take root.

Landing

Before planting in the soil, the stalk must be stored in a cool room so that the buds do not begin to open. Choose a time such that the threat of frost is gone, since young cuttings do not take root well, their roots are weak, and the newly planted plant may die.

Annual seedlings are recommended for planting. The place should be well lit, because the size, quantity and taste of the fruits depend on the presence of the sun. The ideal option is to plant the bushes in an open space, along the fences, which will protect the plants from the wind.

Before planting, the roots need to be soaked for several hours, shorten the cutting so that the ground part is no more than 20 centimeters. Landing holes are dug half a meter deep and of the same diameter, half filled with loose, fertile soil mixed with fertilizers. The distance between the bushes should be about two meters, if less is left, it will be inconvenient for you to harvest.

When planting, keep the cutting tilted, the depth should be eight centimeters above the location of the root collar. It is recommended to immediately water the planted plants, two buckets of water under the bush are enough. So that the yield is high, and the bush takes root faster, cover the soil with humus with a layer of several centimeters.

Further care

If the summer is dry, water the bushes twice a week in the evening. If there is enough rainfall, you will still have to irrigate - four per season will be enough. Water with 4 buckets per square meter.

Dobrynya black currant needs pruning of old shoots, as a high yield can be obtained from new ones. Remove excess branches in the spring before bud break, and in the fall, before covering (if necessary) the bush, so it will overwinter more calmly.

Currant "Dobrynya" loves loose soil, it is sometimes necessary to shovel the bushes. It is obligatory to weed, apply fertilizers to the soil. It is also necessary to carry out preventive work against pests.

The Dobrynya black currant variety of Russian selection has earned excellent reviews. Amateur gardeners approve of it, and it is also in demand in industrial production. According to the sum of its characteristics, the variety is among the best. Dobrynya perfectly tolerates droughts and frosts, gives good yields, has large fruits and good taste.

Breeding history of the variety

The Dobrynya variety was bred at the Lupine Research Institute by Alexander Ivanovich Astakhov, Doctor of Agricultural Sciences. Dobrynya's parents are Raisin currants and numbered 42–7. And in 2004, the variety was included in the State Register of Breeding Achievements and recommended for cultivation in the Central and West Siberian regions. Subsequently, Dobrynya spread throughout Russia. It is also grown in Ukraine.

Characteristics of black currant

For 12 years of cultivation, Dobrynya has acquired an excellent reputation. It can easily withstand frosts up to 25 degrees, and in shelter and below 40 degrees. Resistant to spring frost. It does not die during prolonged drought, although the berries become smaller without watering.

Has a good yield from 1.6 to 2.4 kg per bush. Due to the fact that the bushes are low and they can be planted at a distance of 80 cm, it gives more fruits per unit area. The variety is fast-growing and pleases with the first fruits the next summer after planting. In rainy years, the fruit remains sweet. It is immune to powdery mildew and kidney mites. Bears fruit annually and abundantly.

Features of planting and growing varieties Dobrynya

There are few differences in the agrotechnology of Dobrynya cultivation. And they are explained mainly by the characteristics of the variety. Intensive varieties begin to bear fruit as early as the second year after planting. They require good fertilization and regular pruning. First, only sanitary, and then rejuvenating. In industrial cultivation of this variety, only annual branches are often left when pruning. This makes it possible to get harvests from plants for 12 years or more. Perhaps one of the amateur gardeners would like to conduct this experience.

When planting, 4–5 kg of humus or good, ripe compost and 1 glass of wood ash or any complex fertilizer are added to each hole according to the instructions. Subsequently, both organic and mineral fertilizers are applied annually. This is a prerequisite for obtaining high yields and large fruits.

An important condition for the successful planting of Dobrynya is the correct compaction of the soil. The variety has a rather weak central root and it is required to compact it well without damaging the root hairs. The soil should settle on its own without much external pressure. Therefore, the timing of autumn planting in central Russia is chosen no later than September. And, of course, in the first days after planting, you need daily watering.

Rooted sapling variety Dobrynya

One more important note: in the Dobrynya variety, when planting, two-year-old seedlings take root better. And before planting, it is advisable to hold the roots of the seedling in a solution of Kornevin or another root growth stimulator for a day. This condition is explained by the rather weak ability of the variety to form root hairs when propagated by cuttings, especially in southern climates.

Reviews

The black currant variety Dobrynya continues to take root in our gardens and receives more and more enthusiastic and balanced reviews. Be that as it may, he has already taken a solid position among the demanded varieties. The choice is yours.

Black currant "Dobrynya", which is a fruit and berry crop of Russian selection and has received many positive reviews, is actively used both in amateur gardening and on an industrial scale.

The set of characteristics gives grounds for its classification as the best domestic varieties.

Black currant "Dobrynya":

1. It tolerates both severe frosts and prolonged droughts equally well.
2. It gives good yields on a stable basis.
3. Differs in large size and excellent taste of berries.
4. It is a mid-ripening, early-growing, intensive type.
5. Differs in high resistance to many diseases (especially powdery mildew).

Description of the variety

The weight of the berries - slightly oval, black and shiny - ranges from 5.5-7 g. Being the owners of an elastic dense peel, they do not crack and are characterized by dry separation. Gardeners highly appreciate their pleasant aroma and sweet and sour taste (average taste rating is 4.8 points).

Dobrynya black currant fruits contain up to 6.9% sugar. The content of ascorbic acid in 100 g of berries reaches 200 mg, and the titratable acidity is 2.5%.

The Dobrynya variety belongs to the medium-yielding category: from one bush, you can remove from 1.6 to 2.4 kg of fairly large berries. With an average yield per hectare, up to 10.6 tons of fruits can be harvested, with a maximum yield up to 16 tons.

Dobrynya black currant bushes are erect and compact. Depending on the region of cultivation, they can be weak or medium-sized. Young shoots, which do not differ in significant thickness, are slightly pubescent, olive-violet in color and insignificant shine.

Leathery wrinkled leaves with short teeth are bright green in color and rather large in size. During the flowering period, which occurs in mid-May, from 6 to 10 huge yellowish flowers appear on thick, slightly sinuous and loose racemes.

The bulk of fruits ripening in the second decade of July are concentrated in the middle and upper parts of the cluster. At the base of the hand, they almost never exist.

Suitable region and climate

Black currant variety "Dobrynya" is ideal for growing in the middle zone of Russia. Bred since 2004 by gardeners of the West Siberian region, she still receives their high marks. The variety is successfully grown in the more southern regions of the Russian Federation, as well as in Ukraine.

Breeding history

The creator of the Dobrynya variety is AI Astakhov, a leading specialist of the All-Russian Research Institute of Lupine, who has a Doctor of Agricultural Sciences degree.

For interspecific crossbreeding, he chose a variety-line hybrid 42-7 and his own variety "Izyumnaya", which has very sweet fruits. The hybrid variety Dobrynya was included in the State Register of Breeding Achievements in 2004.

Pros and cons

The Dobrynya black currant variety has a number of advantages:

1. Straight growth.
2. Early maturity (the first berries can be tasted next summer).
3. The presence of large fruits.
4. Excellent taste of berries, which continue to remain sweet even in rainy summers.
5. The compactness of the bush, which saves the planting area.
6. Good winter hardiness, thanks to which the plant tolerates 25 degrees of frost without any problems (at lower winter temperatures, the bushes need additional shelter using insulation material).
7. Equal resistance to spring frosts and prolonged summer drought (in both cases, flowers and ovaries do not drop).
8. Powdery mildew resistant.

Disadvantages of black currant "Dobrynya" are:

1. Relatively low (in comparison with other varieties of this berry crop) yield.
2. The lack of synchronicity in the ripening of the crop, in connection with which it is carried out in several stages.
3. Low transportability of berries, which quickly crumble during transportation, crumple and lose their presentation.
4. The poor survival rate of the planting material, due to the slow formation of the root system, which can wither some time after planting young cuttings to a permanent place. For this reason, there are frequent cases of wilting of early opened buds. To help a young plant take root, experienced gardeners recommend using a root growth stimulant when planting.

Growing

Black currants can be planted both in autumn (for the northern regions, the end of September is suitable, for more southern regions - October-first decade of November), and in spring (at the beginning of April).

At the same time, you should know that in the fibrous root system of this shrub there is no well-developed central root, therefore, in order for the soil to withstand the weight of such a powerful plant that does not have a reliable root support, it must be dense enough and well compacted.

Since mechanical compaction of the soil, carried out immediately after planting young cuttings, is fraught with damage to the roots or root buds that have not yet matured, it is better to rely on its subsidence under its own weight. It has been established that the bushes planted in the fall before the first frost on the soil take root best of all.

Site preparation

The plot intended for growing black currant varieties "Dobrynya" must be:

1. Moderately moistened, with a low (not higher than 2 meters) level of groundwater, since swampy and waterlogged soils are contraindicated for this plant.
2. Protected from strong wind.
3. Sufficiently lit. A relatively light-loving plant can also be grown in shaded areas, but a lack of sunlight can affect its yield.

When preparing the site for planting black currants, you must:

1. Carefully level its surface by filling in the depressions and leveling the bumps.
2. Drain soil prone to flooding or stagnation of spring thawed water by introducing coarse sand, pebbles or small stones into it.

Rules for choosing planting material

Dobrynya black currant seedlings are best purchased either at agricultural fairs or in fruit and berry nurseries.

When choosing planting material, you should know that seedlings are the best:

• two years of age;
• with a well-developed root system, consisting of straight elastic roots 15-20 cm long;
• having from 4 to 5 shoots at least 30-40 cm high.

Given the relatively weak ability of the currant variety "Dobrynya" to give root hairs, before planting a seedling in a permanent place, it is advisable to hold its roots in a solution of a root formation stimulator for a day (for this, the drug "Kornevin" is most often used), and shorten all available shoots so that their length was no more than 20 cm.

Step-by-step planting instructions

1. Before planting seedlings, planting holes are dug in advance, having a depth of no more than 40 cm and a width of 50 to 60 cm.
2. In order to ensure good ventilation of plants, significantly reducing the risk of fungal diseases, a distance of at least 1.5 meters is left between single holes. The row spacing should be between 2 and 2.5 m.
3. To improve the quality and structural characteristics of the soil, wood ash (100-150 g) and compost or rotted manure (4-5 kg) are added to each planting hole. If the planting holes were dug on already fertilized soil, no additional fertilization is required in them.
4. Having examined the roots, they are evenly distributed over the entire width of the planting hole.
5. Holding the seedling in a semi-vertical position (at an angle of 45 degrees to the soil surface), it is buried together with the root collar to a depth of no more than 8 cm. In this case, it is necessary to ensure that the fruit buds remain above the ground level. Only in this case should you expect to get the most powerful shrub.
6. Freshly planted bushes are watered abundantly (the norm is at least 10-15 liters for each plant).
7. The root circle of each seedling is immediately mulched using a thick (10 to 15 cm) layer of earth, dry grass or sawdust.

Care

Regular and abundant fruiting can be achieved with the help of annual pruning, which involves replacing old shoots with young ones.

Photo cropping:

The pruning rules are as follows:

1. The number of branches in a normally developed fruiting bush should be from 15 to 18 pieces.
2. The fruiting period of each shoot is no more than 5 years.
3. Old branches with peeling rough bark must be cut to the level of the soil.
4. To stimulate the growth of young shoots, all branches that are more than a meter in length should be shortened by 15-20 cm.
5. Long branches and root growth can be trimmed during the summer season. Sanitary pruning, which involves the removal of broken and damaged shoots, is performed either in March (until the buds swell) or in late autumn.

Watering

Experienced gardeners recommend watering by pouring water into circular grooves dug around the bushes (at a distance of 20 cm from the tips of the branches).

It should be remembered that drying out of the soil can negatively affect the quality of the fruit: they can become drier and shallower, with hard bones, while prolonged waterlogging (due to flooding and continuous rains) is fraught with wetting and death of the entire bush.

Throughout the growing season, infrequent (no more than once every 2-3 weeks) drip irrigation is quite enough for currants of the "Dobrynya" variety, providing for the introduction of 20 liters of water for each bush.

Abundant (at least 3-4 buckets of water per bush) watering is necessary only during the period:

• fruit set in mid-May;
• pouring berries (in June);
• after the leaves fall (the so-called podzimny water-charging irrigation).

Top dressing

1. In order to stimulate the growth of root shoots, starting from the fourth year of life, the currants are fed with a mineral fertilizer prepared from 10 g of potassium, 3 g of magnesium and 6 g of phosphorus, dissolved in 10 liters of water. Top dressing (at the rate of 2-3 liters per bush) is introduced into the soil of the trunk circle.
2. To stimulate the growth of shoots and rapid budding, at the beginning of March, 40-50 g of urea (in the form of dry granules) is scattered over the surface of the well-moistened soil of the trunk circle. To protect the roots from burns, the plant should first be well watered.
3. Before flowering, currants are fed twice with a liquid aqueous solution of chicken manure or rotted manure.
4. During flowering, foliar feeding is carried out by spraying the leaves with a solution prepared from copper sulfate (10 g), boric acid (2 g) and manganese potassium (5 g), dissolved in 10 liters of water. Fertilizer consumption - 2-3 liters per bush. Top dressing contributes to the production of large, healthy and tasty berries.
5. After setting the fruits, a circular groove 5-10 cm deep is made around the perimeter of the bush and it is well moistened, after which an aqueous solution of bird droppings (prepared at a rate of 1:10) is poured into it.
6. During the entire vegetative period, some gardeners water the currants with bread kvass (2-4 liters per bush) or bury pieces of soaked and fermented bread in the trunk circle.
7. Potato peelings can be put into circular grooves dug along the diameter of the crown, adding dry urea granules to them (at the rate of 10 g per bush).
8. It is useful to plant legumes between the currant bushes (vetch, peas, clover, beans), and in the fall, bury their wilted tops in the aisles. Thanks to these natural dressings, the soil will be enriched with carbon dioxide and nitrogen, activating the activity of beneficial soil microflora.
9. In October, under each bush, you can add 2-3 kg of compost or chicken droppings without embedding them in the soil. This top dressing, which feeds the roots during the winter and early spring period, will decompose on its own under the influence of rain and snow.

Preparing for winter

Currant "Dobrynya" has good resistance to frost and late spring frosts, however, when grown in regions with little snowy winters or in steppe regions, in which the snow cover protecting the shrub from frost can be blown out by strong winds, additional measures are needed to ensure the safety of the plant ...

Winter preparation can be done in one of these ways:

1. The bush, divided into parts (2-3 branches each), is bent to the ground. Branches laid on the ground can be covered with a thick (up to 20 cm) layer of dry grass, coniferous spruce branches or hay, dry soil, old newspapers or an old-fashioned quilted jacket.
2. At the beginning or in the middle of November, each shoot can be wrapped with breathable cloth or agrofibre (the use of plastic wrap should be discarded). Leaving the bush in its natural position, it is only additionally pulled with a rope to the center.

Pests

Currants can be attacked by pests:

1. Caterpillars leaf rollers, gnawing and destroying ovaries and buds. To combat the leaf roll, it is necessary to spray the bushes with a chlorophos solution (30 g per 10 L of water) or an emulsion of DDT (40 g per 10 L of water). Prevention consists of burning fallen leaves (in the fall) and hanging pheromone traps to attract males.
2. Currant kidney moth, the larvae of which in the spring are able to completely eat up all the buds. Control measures: similar to those described above. Preventive measures: cleaning and loosening the surface layer of the soil near the bush during the autumn work; regular sanitary pruning to remove dried old branches.

Diseases

Terry

Currants can suffer from:

1. Terry - a viral disease carried by herbivorous ticks and aphids. The disease is manifested by stretching, deformation and blue discoloration of flowers (from which fruits are never formed), darkening and stretching of leaves, loss of the characteristic currant smell. The bush affected by the disease is subject to immediate uprooting and destruction. Neighboring plants should be sprayed with Vectra or Topaz. Prevention consists in acquiring healthy seedlings, fighting ticks and aphids, and disinfecting garden tools.
2. Goblet rust - a fungal disease that manifests itself by the appearance of yellow-orange blistery swellings on leaves and shoots. Control measures: spraying plants with fungicides "Bayleton", "Hom", "Topaz", 1% solution of Bordeaux liquid or biological products "Fitosporin" or "Fitodoctor". Preventive measures: mowing sedge, on which rust spores mature and winter, timely collection and burning of damaged leaves, regular loosening of the soil under the bushes.
3. Septoria - a fungal disease, manifested by lightening of the leaf plates and the appearance on berries and leaves of small dark spots that have an angular or rounded shape. The fight against the disease consists in spraying the affected bushes with a solution of copper sulfate (40 g per 10 l of water) or the drug "Nitrafen" (200 g per bucket of water). Prevention: sanitary pruning and shortening of long branches, inadmissibility of thickening of plantings.

Collection and storage

It is necessary to collect berries only in dry weather, after waiting for the morning dew to dry.

Dobrynya currants packaged in plastic bags or wooden boxes can be stored in the refrigerator for a long time:

• at zero temperature, it retains its beneficial properties for 45 days;
• at a temperature of -2 degrees - up to 12 weeks;
• deep freeze - up to one year.

Currants can be saved by rubbing them with sugar or making aromatic jam, jam or jelly from them.

Black currant is one of the most beloved berries in our region.

Large burgundy-black "beads" of the bush, in addition to rich taste, contain a record amount of vitamins.

The berry is often successfully used in the prevention and treatment of many diseases.

Black currant - a fairly young culture. Nowadays, the berry is very popular with gardeners. There are already more than two hundred varieties of currants, the selection continues to this day. New varieties appear every year.
