Currant and gooseberry hybrid: characterization and cultivation
Most gardeners and gardeners, one way or another, strive to stand out among their friends and acquaintances with some unusual plant. In this case, scientists-breeders come to the rescue, who create outlandish hybrids in their scientific laboratories, breeding interesting varieties by crossing. One of these creations is yoshta - a mixture of currants and gooseberries.
What is this plant?
Yoshta is a crossed species obtained from two types of gooseberries (common and splayed) and the usual blackcurrant. The hybrid is named after two German crops: Johannisbeere (currant) and Stashelbeere (gooseberry). The plant was created in the laboratory of the world-famous biologist Rudolf Bauer and presented to the general public in the late seventies of the last century.
Over the past decades, yoshta has significantly expanded its geography - now it is widely cultivated in Russia and other countries of the post-Soviet space. The berries of this unusual plant are consumed raw, canned and frozen for the winter.
The hybrid is a powerful shrub with a strong root system. The plant is resistant to low temperatures, and in addition, it is immune to most types of fungal and bacterial diseases. It does not require special landing conditions and is quite unpretentious in care.
The crown is large, spreads over 2-2.5 meters. Shoots grow up to one and a half meters, and under favorable conditions, the length can be much longer. Up to 25 large shoots grow on a dense stem, which are formed as the yoshta grows. The roots go down to 40-50 cm into the ground. The leaves have a dark green saturated shade with light veins without the aroma typical of currants and stay on the branches until the onset of cold weather.
Yoshta blooms in large inflorescences of bright yellow-red hues, the berries are black or dark purple with a rather dense skin. The mass of each reaches 5 g, has a pleasant taste and a tart nutmeg smell. It is characterized by low fall, so the ripe fruits do not fall from the tree even after reaching technical maturity. The culture gives a consistently high yield for 20-30 years.
Varieties
The most widespread are the following varieties of yoshta.
EMB
A well-known hybrid that was bred in the UK. This is a medium-sized plant that reaches 1.6 meters in height, crown diameter - up to 2 meters. The branches are strong, tightly attached to the main trunk, so they do not require a garter.
The berries are quite large, the taste is sour, the weight of each fruit is approximately 4.5 g, although under favorable conditions it can reach 12 g. The plant gives a consistently high yield - up to 10 kg of fruits can be harvested from each bush.
Yoshta begins to bloom already in early April, therefore, with a sharp drop in temperature, you should cover the branches with agro-canvas - otherwise the flower stalks will fall off and the ovary will not be able to form.
"Kroma"
This variety comes from Switzerland. It is a low plant with a spreading crown, its diameter reaches 2 m.The shoots are strong and dense, the berries visually resemble currants, have a sweet and sour taste, each weight is approximately 6-7 g.
The yield is relatively low - no more than 5 kg of fruit can be harvested from one bush. Variety "Kroma" is highly resistant to temperature fluctuations and most garden pests.
"Rext"
This variety is often planted for decorative purposes - the plant not only produces juicy and fragrant fruits, but also serves as a real decoration of the garden landscape. The bush is undersized - its height, as a rule, does not exceed 1.2 meters, the branches are sprawling, strong. The berries have an amber or golden hue characteristic of gooseberries, sweet with a tart flavor, the weight of each fruit varies from 5 to 9 grams.
"Rekst" is characterized by high productivity - from 7 to 10 kg of crop can be harvested from one small bush. The plant prefers shady areas, in the sun its leaves can burn.
"Yochilina"
One of the highest-yielding varieties, which is most popular with our compatriots and has the most positive reviews. The plant grows up to 1.5 meters, while it forms a dense and rather sprawling growth, so the plantings should be thinned out from time to time, otherwise the berries will be too small.
The fruits are quite large, under favorable conditions they reach a weight of 12 grams, while 7-8 kg of juicy berries can be collected from one tree.
The compatibility of different varieties with each other is quite high.
growing conditions
Yoshta grows in most European countries, it is grown everywhere in Russia, especially often it can be found in the southern regions and regions of the Central Strip.This is due to its good frost resistance and the ability to endure long winters without compromising its condition, growth and development.
In the north and in Siberia, it is better to grow yoshta in greenhouses and greenhouses, since the yield in open ground will be 1.5-2 times lower. Yoshta grows very well in the south, however, those who plan to cultivate this plant in a hot climate should keep in mind that the shrub does not tolerate direct sunlight, so seedlings should be placed in shady areas.
cultivation
Yoshta is planted either in early spring, immediately after the snow melts, or in autumn - in both cases, it takes root quite quickly and shows good growth. When buying, special attention should be paid to the roots - they should be large and healthy, if the seedling offered to you looks wrinkled or dried up, and the root system is weak and unformed - it is better to refuse to buy such a shrub.
On the day of planting, the roots of the plant should be soaked for a couple of hours in a solution of prepared fertile soil - they should be thoroughly soaked and straightened. It is desirable to add humus, compost and mineral supplements to the prepared hole.
Yoshta, unlike currants, has an increased need for potassium, so it must be brought into the hole before planting.
In general, you can use the following composition of fertilizers:
- organic - 5 kg;
- potassium sulfate - 40 g;
- superphosphate - 60 g.
The earth in the planting hole should be watered abundantly, and after planting the plant, cover with mulch.
If you plan to plant several bushes, then a distance of 1.5-2 meters should be maintained between them.Keep in mind that the planting pit should be much more spacious than for gooseberries or currants, since much more fertilizer is applied to each, this is due to the need to increase the feeding area, which is very important for getting a bountiful harvest.
Under the bush, a small mound of humus and peat should be formed - such a measure will stimulate the formation of young shoots that are used to propagate the culture. Caring for yoshta is not particularly different from caring for related plants, however, the hybrid requires more abundant watering, so the shrub should not only be regularly irrigated, but also sprinkled with mulch, which will prevent excessive evaporation of moisture.
If you use mulch, there is no need for occasional loosening and weeding, and it is important to reapply it from time to time, because as the plant grows, the mulch shrinks and partially decomposes, providing additional nutrition to the bushes.
The plant responds well to top dressing, the infusion of bird droppings or mullein, introduced from the very first spring days, is most suitable for it.
The plant reproduces in several ways.
- cuttings - for this, young shoots cut in winter are used. Immediately after cutting, they should be dipped in water for 3-4 hours, and then put in a bag and placed in a cool place until spring. In March, cuttings are planted in greenhouses, and in autumn they are transferred to open ground to a permanent place.
- layering - in this case, two-year-old shoots are chosen, in the lower part of the yoshta they are pressed to the ground, fixed with a log or stone and sprinkled with fertile soil.During the entire growing season, they must be watered and fertilized - in this case, in the fall, the place of contact with the ground will give roots, and many young shoots will appear from the buds. Thus, in the fall, a strong seedling will be ready, which should be cut off and transplanted to a permanent place.
- division - a fairly effective and simple method. In early spring or autumn, the whole bush should be dug up, cleared of the ground and, using an ax or a sharp knife, divided into parts so that at least 3 large roots and several stems with buds are preserved in each.
Sometimes there are situations when yoshta should be transplanted. There may be several reasons: an old bush, an initially incorrectly selected place, severely depleted soil, or the need to use the site for another purpose. It is better to replant bushes in autumn, the plant must be transferred along with an earthen clod. After transplantation, you should immediately remove the old branches, shorten the young ones, and then moisten them abundantly.
And, of course, like any other horticultural crop, yoshta needs periodic pruning, especially since the currant and gooseberry derivative, like its daughter plants, tend to grow rapidly and form numerous shoots. Molding begins in the spring - in the year following planting. At this time, 3-5 of the most powerful branches are left, and all the rest are cut off.
The following year, the same stems and 3-5 more young shoots are left, and this is repeated every year. Thus, an adult plant will have 18-20 stems of different ages by 7 years old.At this time, the fruiting of the stem begins to stop and even decrease, therefore, starting from this age, the oldest branches can be removed, leaving more room for new ones. This approach to the formation of the bush will allow you to achieve maximum productivity and exceptional decorativeness of the shrub.
Disease and pest resistance
Like any other hybrid, yoshta is distinguished by good resistance to most diseases of horticultural crops and their pests. However, it is impossible to completely exclude the possibility of damage, therefore, special attention should be paid to preventive measures. To do this, annually the leaves and stems are sprayed with solutions of copper sulfate, nitrofen and Bordeaux mixture.
Processing should be carried out in early spring before the opening of the kidneys, if this moment was missed, then you can spray yoshtu in the fall after harvest.
If it was not possible to avoid problems with insects, then ready-made store trains "Kleshchevit", "Decis" or "Agravertin" will help to drive away uninvited guests. Unfortunately, yoshta sometimes encounters fungal diseases. Most often, she suffers from septoria, powdery mildew, anthracnose and rust.
If you notice the disease in the early stages, then it can be easily cured with the help of fungicidal preparations "Maxim", "Bayleton" or "Fundazol".
Collection and storage of berries
The fruiting of yoshta lasts on average three weeks, but the fruit ripens at different times, so you can harvest from mid-July to the first decade of September. It is noteworthy that the yoshta berries do not fall, so it is possible to collect not as they ripen, but if possible, however, it is not worth delaying the collection, because with prolonged hanging, the skin of the berries becomes denser.And any attempt to collect a late harvest sometimes ends with bursting of berries, in this case, experienced gardeners recommend cutting them off with brushes, and already at home, carefully and carefully separate them from each other.
Yoshta berries are very healthy and nutritious, especially when raw, however, many housewives preserve them for the winter, prepare jams, jams and compotes.
By the way, if you let the berries hang on the branches longer, they will become slightly dried and look like raisins, in no way inferior to it in sweet and tart taste.
