Not the most beloved berry bush in the recent past again wins the love of gardeners, confidently taking positions among the leaders. The fruits of the universal gooseberry of the Yubileiny variety (synonyms of Grossularia, Ribes uva-crispa Yubileyniy) are used for fresh food, delicious and beautiful jams and amber-colored jams are cooked from them, an excellent wine is made from gooseberries, thanks to the dense skin it is an ideal product for deep freezing. The berry retains its excellent presentation for a long time.
Breeding history
The author of a magnificent variety with amber berries is MI Kashichkina, breeder of the All-Russian Research Institute of Horticulture named after V. I. V. Michurin. The variety is obtained by crossing Bedford yellow and Houghton. Jubilee was approved for use in 1965.
Description of the variety
Compact, vigorous, slightly spreading bushes have an average degree of thickening and branching. Shoots are covered with often spaced double and triple thin but strong spines. The surface of the thorns is matte, dark-colored, with a perpendicular arrangement relative to the branches, sometimes directed downward. Only the vertex assemblies remain studless.
The bushes are covered with dark green leaves of a slightly concave type, of medium size and density, with a shiny smooth surface. Growing, slightly curved shoots are colored in light green tones, devoid of pubescence, at the lignification stage, the bark acquires a light gray color with brownish tints. The gooseberry blooms with small flattened pale flowers with an anthocyanin "smear" at the base. Flowers are collected in one-two-flowered inflorescences. The variety is characterized by a high shoot-regenerating ability.
Characteristics of berries
A large (4-5.4 g) round or round-oval berry is colored amber-yellow, diluted with medium-branched lighter veins. The pulp is covered with a dense skin, with a rare glandular pubescence and a light bloom of prune.
Taste qualities
The juicy pulp of a delicate consistency has a sweet and sour taste, is filled with a large number of seeds and has almost no aroma. The berry contains sugars (9.2%), titratable acids (2%), ascorbic acid (11.8-40.0 mg / 100 g). Assessment of tasters - 4 points.
Ripening and fruiting
The variety belongs to the mid-season category - the harvest is harvested in the second half of July. The beginning of fruiting occurs 2-3 years after planting.
Yield
Jubilee gives bountiful harvests, subject to the rules of agricultural technology. 4.2 kilograms of fruits are harvested from one bush, over 14 tons from one hectare.
Growing regions
Gooseberries are adapted for cultivation in the Central Black Earth Region.
Landing
Well-lit places are chosen for planting, since the gooseberry loves the sun, and the more it is, the sweeter and larger the berry. The shrub does not develop well in swampy lowland areas, it does not tolerate the proximity to groundwater and currants. The soil for the shrub should be with a neutral level of acidity, loose, breathable and fertile.
The ideal age of seedlings is 2-3 years with a root system of at least 20 cm.The most successful time is autumn 1-1.5 months before the onset of cold weather. During this time, the seedling will take root, get stronger, and safely survive the winter. In spring, the plant will enter the beginning of the growing season in time. Planting in spring is also possible, but the seedling will need a period of adaptation and part of the season will be lost.
The optimal size of the planting pit is 40x40 cm or a little more. The dug hole is filled by ⅓ with a mixture of earth, peat and rotted manure. Organic matter (humus, compost, bird droppings), superphosphate, potassium salt and wood ash are added to the rest of the soil. If the acidity of the soil is increased, then add chalk, lime or dolomite flour. After planting, the near-stem circle is well watered with warm water, no more than five buds are left on the seedling.
Growing and care
The variety is self-fertile, but cross-pollination always increases yields. Neighborhood with other varieties of the same flowering period will benefit the Jubilee. All gooseberry care consists of traditional activities:
loosening and feeding;
weeding and mulching;
preventive treatments;
sanitary and formative cuttings.
Watering of young first-year plants is carried out as the soil dries up - a weak root system is not able to extract moisture from the depths. Adult bushes are watered no more than four times per season.
In the spring, during flowering and budding.
While pouring berries.
After harvest.
In the fall, to help the plant through the winter.
During drought, irrigation is carried out much more frequently.
Top dressing begins in the third year after planting, if the planting pit has been filled correctly. In spring, the plant needs nitrogen fertilizers to build up green mass. However, if the leaf is large, the foliage is good, then the introduction of nitrogen is not only unnecessary, but may be unnecessary. During the period of ovary formation, the bushes are fed with potassium-phosphorus compounds. In the fall, 3 buckets of humus are poured under each bush.
Sanitary pruning keeps bushes free of broken, diseased, dry branches. During the forming pruning, excess shoots older than 4-5 years and branches growing inward are removed. As a result, the bushes should have 15-20 different-aged shoots, well ventilated and illuminated.
Disease and pest resistance
The cultivar is considered to be relatively resistant to diseases, for example, to its main enemies - American powdery mildew and anthracnose. Of the pests, leaf-eating aphids, moths and sawflies are dangerous for him. Preventive treatments with insecticides and fungicides will help protect plants from damage.
In order for the gooseberry to produce a good harvest, it is necessary to devote time to disease prevention.
Resistance to adverse climatic conditions
Jubilee has good winter hardiness, which allowed him to master even the gardens of Siberia.
