Red currant Tatyana, authored by T.V. Romanova and S.D. Elsakova, was bred at the Branch of the All-Russian Institute of Plant Growing at the Polar Experimental Station, near the city of Kirovsk. The ancestors of the variety were Victoria red and Kandalaksha. It was registered in the Russian State Register in 2007 as a selection achievement intended for cultivation in the Northern region.
Description of the currant variety Tatyana
The Tatyana currant bush forms straight shoots, forming slightly spreading but vigorous plants. The branches have a matte bluish tint, due to the presence of anthocyanin pigments, and are distinguished by a strong structure and weak pubescence.
The medium-sized ovoid buds are also distinguished by medium fluff. The large, three-lobed leaves have an intense matte green color on top and are covered with a white coating on the underside due to pubescence. The concave central vein of the leaf forms a notch at the base. Short, rounded teeth alternate with small cutouts.The refined pink petiole is characterized by considerable length.
During the flowering period, the plant of the Tatyana variety is covered with large, dim flowers, which then form uncut ovaries with pronounced pubescence. The sepals and awn of the brush are of medium size.
Tatyana currant berries are characterized by medium size and thick skin.

The winter-hardy crop Tatyana is recommended for cultivation in areas where frequent temperature changes are observed:
- sudden cold snaps in the spring;
- thaws in the cold season.
Characteristics
Reviews of red currant Tatyana confirm the excellent resistance of the variety to prolonged rains and significant wind loads. Such climatic phenomena do not affect the process of ovary formation, which makes it possible to obtain consistently high berry yields in any year.
Drought resistance, frost resistance
The Tatyana variety is not intended for cultivation in arid southern regions, but is highly valued for its excellent winter resistance in harsh conditions. It is noted that specially adapted Russian currant varieties are able to tolerate frosts down to − 50 °C.
Productivity of the variety
Red currant Tatyana shows excellent productivity: on average, each bush produces about 5 kg of berries (16.5 t/ha). Even fully ripened fruits are not prone to shedding.
In terms of harvest timing, the crop is classified as mid-season; in the harsh conditions of the north, it bears fruit later. Mass flowering begins on May 10-31; in late spring it can cover part of June. The ovaries are formed within 14 days, the berries are collected from the end of July to the beginning of September.
Application area
The Tatyana red currant culture is suitable for industrial cultivation and has also proven itself to be an unpretentious variety for a summer house or a plot of land at a country house. Its berries are good for fresh consumption, making jams, preserves, confitures, making desserts and freezing.
Pros and cons of the variety
The main advantage of the Tatyana currant variety is its high resistance to bad weather, most diseases and pests. Other advantages include:
- self-fertility;
- undemanding to nutrition;
- lack of tendency to shedding and damage of berries, high yield safety;
- excellent taste characteristics of berries;
- high content of sugars, organic acids, iron, potassium, iodine and pectins.
The disadvantages of the crop include the formation of relatively small berries, as well as the inability to obtain the maximum yield in the conditions of the northern regions. In harsh climates, red currant Tatyana shows a small, although stable, yield.
Reproduction methods
The easiest way to propagate red currants is to root horizontal cuttings from an adult bush. To do this, well-developed shoots are placed in previously prepared furrows 10-15 cm deep without being disconnected from the mother plant, pinned tightly with hooks and sprinkled with soil in the middle part.
The upper end of the branch should remain above the surface of the substrate. When it grows to 10 cm, hilling is carried out, which is repeated after 2 weeks. In autumn, rooted shoots are separated from the mother bush and transplanted to a permanent place.
Planting and care
For planting, it is optimal to use seedlings with a well-developed root system: the rhizome should reach a length of at least 15 cm. The optimal place for growing Tatyana currants is well-lit hills with loose soil. Sandy loam and loam are preferred as substrates.
Before planting, it is useful to dip the rhizome of the Tatyana currant seedling in a clay mash. This procedure helps protect developing roots from rotting and drying out, and also prevents the penetration of pathogenic microorganisms into plant cells.
Damaged and dried shoots must be removed. The above-ground part of the currant is cut to a height of 30-35 cm, which ensures the presence of at least 2-3 buds on each shoot.
The pit for the Tatyana variety must be prepared in advance, at least 14-21 days in advance. Its parameters are 60 cm in width and length, 40 cm in depth. You need to add 1.5-2 buckets of humus to the bottom.
Immediately before planting a red currant seedling, the compost is mixed with soil, adding mineral fertilizers depending on the characteristics of the substrate. The plant is placed in a hole, preventing the roots from bending upward, sprinkled with soil and watered abundantly. Each bush requires 20-30 liters of water.
Aftercare
The red currant variety Tatyana is undemanding in care, but requires timely implementation of basic procedures:
- To prevent branches from breaking off with the berry harvest, a supporting frame is built.
- Pruning is carried out after the bush has fruited, the shoots are shortened to a height of 25-30 cm, and at least 2-3 buds should remain on each stem (optimally 5-6).
- Watering is carried out according to need, during periods of prolonged rains they are stopped, the rest of the time it is important to keep the soil moist.
- Loosening is done with care so as not to damage the developing root system. The event is carried out after watering or rain.
- Summer feeding includes spraying the root zone with a solution of zinc sulfate and boric acid (at the rate of 2 g of each microelement per 10 liters of water) with the addition of manganese (5 g per bucket of liquid). Each plant consumes from 0.5 to 0.7 liters of solution.
- Autumn fertilizing includes the application of 2-2.5 c/ha of phosphorus-containing fertilizers with an acidic pH and 1-1.5 c/ha of potassium.
Nitrogen fertilization is carried out before the start of the second growing season. It allows you to accelerate the growth of the bush and the set of new shoots. To feed red currants of the Tatyana variety, the addition of ammonium nitrate in the amount of 1.5-2 c/ha will be quite sufficient.
Pests and diseases
The description of the red currant variety Tatyana indicates that it is extremely resistant to most pests and fungal pathologies. To avoid infection, the plant needs regular preventive examinations. If you suspect a disease, it is enough to spray the crop with a solution of laundry soap or sprinkle the leaves with fresh ash.
Conclusion
Currant Tatyana is a mid-season, high-yielding variety that has proven itself well in the northern regions. It withstands temperature changes, prolonged rains, frosts and thaws. The shrub is suitable for cultivation on farms and in summer cottages; during the cultivation process it is necessary to prevent nutritional deficiencies in order to avoid loss of berry harvest.
