This variety of large black currant deserves excellent reviews from gardeners and is in demand on an industrial scale. In terms of general characteristics, Dobrynya belongs to the category of the best. Differs in good productivity, sweet fruits and the possibility of growing in most domestic regions.
Breeding history
To the author Astakhov A.I. VR Williams, it was possible to get a hybrid by crossing two types of currants: a hybrid 42-7 and a sweet variety Izyumnaya.
Since 2004, the Russian state register has recommended a hybrid for planting in the gardens of the Moscow region, in the middle lane and in the southern part of the country. Now the Dobrynya hybrid is cultivated in many Russian regions, as well as in Ukraine.
Description of the variety
A medium-sized and compact bush reaches up to 170 cm, but this figure may depend on the climate in the area where the currants are grown. The shrub has unusually colored young twigs - a violet-olive shade with a characteristic shine.
The leaves are three-lobed, green, large or medium in size. The flowers grow large, cream-colored. The brushes are dense, with the number of fruits from 6-10 pcs. When the berries are detached from the stalks, it is always dry in the place of separation.
Characteristics of berries
Black fruits with firm, shiny skin. The size of the oval berry is extremely large, weighing 2.6-6 g.
Taste qualities
Under the elastic cover, there is a greenish sweet-sour pulp with several small seeds. The taste is rated by tasters at 4.9 points out of 5 probable.
Ripening and fruiting
A medium-ripening currant variety yields a harvest next year after planting. The fruits ripen in stages from the end of July to the second decade of August. Bushes can be planted, maintaining a distance of 80 cm, thereby increasing the number of fruits on each unit of area.
Yield
This indicator for Dobrynya is high, on average 106 c / ha and 1.6 kg per bush. The maximum yield is 16 tons per hectare and 2.4 kg per bush. Yields are affected by temperature changes and irregular watering.
Landing
In order for the acquired seedlings to begin better, planting must be done correctly.
Prepare planting holes in advance with a circumference of 0.55 m and a depth of 0.4 m. The distance between the holes should be from 1.5 m so that the plants do not compete and do not take away nutrients from the “neighbor”. The recommended row spacing is about 2.25 m. With this planting scheme, shrubs are less likely to get sick, and their care is easier.
A perennial berry needs to take a lot of nutrients from the soil. Before placing in the holes, it is recommended to add 0.5 buckets of humus mixed with a full glass of wood ash.
Before planting, illiquid processes are removed, all formed sections are sprinkled with charcoal wood powder.
The seedling is placed in a hole, spreading long roots along its diameter. The plant itself is placed in a hole at a 45-degree slope.The root collar is left to rise 7-8 cm above the soil.
The earth layer is compacted without pressure.
1.5 buckets of water are poured under each seedling.
The area of the trunk circle is mulched.
Growing and caring
There are not so many differences in the agricultural technology used when growing this currant. All of them are associated with the characteristics of this variety. Dobrynya requires dense feeding and timely pruning. First sanitary, and then rejuvenating.
The taste and size of the crop is influenced by the appropriate irrigation regime. With a lack of moisture, the crop becomes hard, and otherwise cracking may occur. Stagnation of water in the deep layers of the soil promotes rotting of currant roots and the death of shrubs.
An earthen rim is created around the trunk circle, which retains moisture after watering. Black currants need to be watered once every 2-3 weeks (look according to the weather). At the rate - 1 bucket for a separate seedling.
But there are also periods when Dobrynya needs more water (up to 40 liters):
second half of May;
early June, during the ripening of berries;
after falling leaves.
Black currants are fed according to the following scheme:
in the spring, after watering, a couple of st. l. dry urea;
when brushes are formed, organic matter is added to the soil - cow dung or chicken droppings aged in water;
when the flowers bloom, you need two fertilizing with liquid organic matter;
foliar nutrition will not be superfluous, stimulating the formation of ovaries and the yield of Dobrynya - 10 g of copper sulfate are dissolved in a bucket of water, 2 g of boric acid are added and 3 g more potassium permanganate, for each bush you will need 2.5-3 liters of solution;
after the formation of the fruits, the near-stem circles are sparingly watered and fed with bird droppings;
before wintering, you will need 3 kg of bird droppings (compost), which are not introduced into the ground.
After planting, the soil is supposed to settle naturally, without strong pressure from the outside. Therefore, in the middle zone of the Russian Federation, planting in autumn is carried out no later than September. In the early days, the seedlings are watered daily.
Disease and pest resistance
The variety is resistant to infection with powdery mildew, fungus, anthracnose. But these berry bushes can infect a bud mite.
In early spring, before the buds open, you need to process the bushes with a light solution of potassium permanganate or Bordeaux liquid.
Preventive spraying is also carried out in the fall, after the shoots have dropped all the foliage.
If signs of disease appear on the foliage and trunks of the Dobrynya hybrid, special fungicides will have to be dealt with.
Currant is one of the most favorite crops of gardeners, it can be found on almost any personal plot. In order for the currant berries to be tasty and large, and the bush itself to be healthy and strong, you should properly care for, treat and protect the plant from harmful insects. It is important to recognize the signs of the disease in a timely manner and begin treatment in the early stages of plant damage.
Resistance to adverse climatic conditions
This large currant has excellent cold resistance. It can hibernate without shelter in regions where the temperature does not drop below -25 degrees Celsius in winter. In colder areas, the berry must be covered before the onset of frosty days.
Neither spring cold snap nor short-term drought in summer have a negative impact on this variety. Under unfavorable conditions, a prolific hybrid does not shed flowers and crops. During rainy periods, the berries retain their sweetness.
Review overview
The black currant variety called Dobrynya consistently receives many well-founded rave reviews.
Berries are known for their medicinal properties and benefits for the body. Currants contain a lot of ascorbic acid and other valuable active substances.
There is a lot of benefit in the foliage itself on the bushes. Therefore, black currant is found in virtually every garden. And even when the plot is small, there is still a place for a couple of bushes of a fruitful perennial.
The fruits are usually eaten fresh, and they are also used for making jam, delicious jams, dense jam and rich compotes. The frozen berries of this hybrid variety retain their useful qualities even during the defrosting process.
The marketability of berries is high, but large currants are poorly preserved during transportation.
Another disadvantage is that the root system is sluggishly forming in the Dobrynya shrub, which somewhat complicates the adaptation period in a permanent place.
