The ancestors of the variety were Victoria Red and Kandalaksha. In the State Register, it was registered in 2007 as a breeding achievement intended for cultivation in the Northern region.
Description of the currant variety Tatyana

- sharp cold snaps in the spring;
- thaw during the cold season.
Features
Reviews of the red currant Tatyana confirm the excellent resistance of the variety to prolonged rains, a significant wind load. Such climatic phenomena do not affect the process of formation of ovaries, which makes it possible to obtain consistently high yields of berries in any year.
Drought resistance, frost resistance
The Tatyana variety is not intended for growing in arid southern regions, but is highly valued for its excellent resistance to wintering in harsh conditions. It is noted that specially adapted currant varieties are able to tolerate frosts down to −50 °C.
Productivity of the variety
Redcurrant Tatyana shows excellent yield: on average, each bush brings about 5 kg of berries (16,5 t/ha). Even fully ripened fruits are not prone to shedding.
According to the timing of the return of the crop, the crop belongs to the middle-ripening, in the harsh conditions of the north it bears fruit later. Mass flowering begins on May 10-31, in late spring it can capture part of June. The ovaries are formed after 14 days, the berries are harvested from late July to early September.
Application area
Tatyana’s red currant culture is suitable for industrial cultivation, and has also proven itself as an unpretentious variety for giving or a plot at a country house. Its berries are good for fresh consumption, making jams, marmalades, marmalades, desserts and freezing.
Pros and cons of the variety
The main advantage of the currant variety Tatyana is its high resistance to bad weather, most diseases and pests. Among other advantages, it should be noted:
- self-fertility;
- undemanding to food;
- no tendency to shedding and damage to berries, high yield safety;
- excellent taste indicators of berries;
- high content of sugars, organic acids, iron, potassium, iodine and pectins.
The disadvantages of the culture 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 a harsh climate, redcurrant Tatiana shows a small, albeit stable, yield.
Methods of reproduction
The easiest way to propagate red currants is to root horizontal layers from an adult bush. To do this, well-developed shoots are placed in pre-prepared furrows 10-15 cm deep without detaching from the mother plant, pinned tightly with hooks and sprinkled with soil in the middle part.
The top end of the branch should remain above the surface of the substrate. When it grows up to 10 cm, hilling is performed, 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. As a substrate, sandy loam and loam are preferred.
Before planting, it is useful to dip the rhizome of a currant seedling Tatiana in a clay mash. This procedure allows you to protect the developing roots from decay, drying out, and also prevents the penetration of pathogenic microorganisms into the cells of the plant.
Damaged and dried shoots must be removed. The aerial 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.
A pit for the culture of 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. 1,5-2 buckets of humus must be added to the bottom.
Immediately before planting a red currant seedling, the compost is mixed with the ground, adding mineral fertilizers to it, depending on the characteristics of the substrate. The plant is placed in a hole, preventing the roots from bending up, sprinkled with soil and watered abundantly. Each bush needs 20-30 liters of water.
Aftercare
The red currant variety Tatyana is undemanding in care, but needs the timely implementation of basic procedures:
- To prevent branches from breaking off with a harvest of berries, a supporting frame is constructed.
- Pruning is performed after the fruiting of the shrub, 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 done as needed, during periods of prolonged rains they are stopped, the rest of the time it is important to keep the soil moist.
- Loosening is carried out with care so as not to damage the developing root system. The event is carried out after watering or rain.
- Summer dressings include spraying the root zone with a solution of zinc sulfate and boric acid (at the rate of 2 g of each trace element per 10 liters of water) with the addition of manganese (5 g per bucket of liquid). For each plant, from 0,5 to 0,7 liters of solution is consumed.
- Autumn feeding includes the application of 2-2,5 q/ha of phosphorus-containing fertilizers with acidic pH and 1-1,5 q/ha of potassium.
Nitrogen fertilization is performed 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 the red currant of the Tatyana variety, the introduction of ammonium nitrate in the amount of 1,5-2 centners / 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. In order to avoid infection, the plant needs regular preventive examinations. If a disease is suspected, it is enough to spray the culture with a solution of laundry soap or sprinkle the leaves with fresh ash.
Conclusion
Currant Tatyana belongs to the mid-season high-yielding varieties that have proven themselves well in the northern regions. It endures temperature extremes, prolonged rains, frosts and thaws. The shrub is suitable for cultivation in farms and cottages, in the process of cultivation it is necessary to prevent a lack of nutrition in order to avoid loss of berry crops.
