Each gardener wants to grow grapes on his plot, which will not only differ in the attractive shape of the clusters, good fruit taste, but also do not contain bones. Since a large number of large seeds can significantly spoil the overall impression of the grapes. These varieties include the seedless Jupiter grapes described below.

Biological description of the grape variety Jupiter

Jupiter grape is used as a table variety and for making wine.

One of the popular and best seedless table grape varieties - Jupiter, which due to frost resistance is the undisputed favorite in temperate latitudes. The grapemakers are breeders John R. Clark and James N. Moore from the University of Arkansas, USA. To obtain a hybrid, grapes such as V. Vinifera and V. Labrusca were used.

Fruiting the grapes begins in the third year after planting, and with proper care - in the second. The vegetation period ranges from 105 to 120 days. Harvest can be at the end of July.

Shrubs of Jupiter with a well-developed root system are characterized by an average force of growth. The vine is light brown in color. The plant is decorated with green three-bladed, slightly dissected leaves. Bisexual flowers that do not require additional pollination. Medium density clusters have a shape in the form of a cylinder or a cone and uniform density. Cluster weight varies from 200 to 500 g. 3-5 shoots can be tied up on the shoots, so there is no need for rationing, as with proper care the plant can easily cope with the load. Up to 40 holes should be left on the vine.

Characteristics of berries

Oval-shaped berries are located tightly in a brush to each other, so the cluster is compact and accurate. The weight of one fruit is 4-5 g, which is considered to be a high indicator for a raisin. Attention is drawn to the process of ripening berries: in technical maturity, their skin has a red or pink color, which at the time of biological maturation becomes dark blue. This helps to correctly determine the time of harvest.

In the berries of Jupiter almost no bones

The density of the skin does not give the aspen families to destroy the harvest of tasty fruits. The fruit has no pits, but may contain a small amount of rudiments. Juicy pulp has a fleshy structure, sweet taste with an exquisite touch of nutmeg and a medium isabel tone.

Indicators of sugar content do not exceed 21%, and the volume of juice acidity is 6 g / l.

The strengths and weaknesses of the raisins

The main advantages for which the variety is recommended for cultivation are:

  • early term entry into fruiting;
  • high yield indicators 200-250 centners can be obtained per hectare;
  • the good rooting cuttings and aging of shoots, even in regions with a harsh climate;
  • preservation of taste and presentation during transport over long distances;
  • frost resistancethe ability to withstand up to -26̊С, in connection with which does not require additional shelter;
  • great resistance to cracking berries with sharp fluctuations in temperature and humidity;
  • the versatility of the berries used both fresh and used for the manufacture of homemade wine and high-quality raisins, distinguished by sweetness and long shelf life;
  • attractive external characteristics of vines and berries provide an opportunity to use the vineyard for decorative purposes.
Variety Jupiter has a very good taste - a combination of nutmeg, strawberry and black currant

In addition to the advantages, it is important to identify and disadvantages, namely:

  • shedding of fruits upon ripening, therefore, it is necessary to monitor the growth process, taking the crop as soon as the berries acquire a bright blue color and are filled with juice;
  • average resistance to mildew, Oedium and gray rot, why bushes need regular treatment to eliminate the loss of crop risk.

Landing technology

Young seedlings better planted in the spring. During the summer season, the plant will take root in the soil and acclimatize to the external environmental conditions. It is possible to carry out planting in the fall, only to carry out all the measures for the protection of grapes bushes from low temperatures.

The main condition - to correctly determine the location for planting bushes plants. Choosing a site to give preference to the sunlit and protected from the wind areas.

Before planting, a Jupiter grape sapling must be kept in water for several days, so that it will absorb the required amount of moisture.

Stages of the landing process:

  1. Prepare a plot removing all weed vegetation and digging the soil deep.
  2. 2-3 weeks need prepare the pits observing the distance between them from 2 to 4 m.
  3. Put crushed stone on the bottom of the hole up to 10 cm from above pour the composition of humus and fertile soil and cover with earth, which will separate the roots of the seedling from the fertilized layers.
  4. Insert a peg on the north side, that in the process of growth will serve as a reliable support.
  5. Before landing put the seedlings in water or solution promoting fast growth and root formation.
  6. Set sapling so that the point of divergence of the shoots on the seedling remains at ground level. Fill gently with earth, adding water for greater soil density.
  7. Then pour on fix pegs and mulch the soil fertilized with nutrients.
Growing grapes in the first year is an important step in the development of young plants. Therefore, you need to care for the vineyard from the moment of planting, creating comfortable conditions for it.

Care for a young and mature vine

The grape variety Jupiter is not considered capricious in the care, but for the formation of a high-quality high-quality harvest requires compliance with certain rules of care

  • provide the plant with moisture at the time of bud break, after flowering and during the growth of the fruit, by means of high-quality irrigation, using water at room temperature;
Before and after harvesting, this grape variety should be well watered.
  • clear territory plant growth from weeds;
  • mulch the earth to preserve the structure of the soil, the proper operation of its microflora, retaining moisture and blocking weed crops;
  • realize root and foliar feeding essential nutrients;
  • prune the vines, shortening shoots by 6-8 buds, which will help stimulate plant growth to increase yields;
  • remove weak shoots in spring, so that they do not pull out the plant resource;
  • perform green operations which include debris, pinching growth points and staving;
  • spend preventive spraying to prevent the vineyard from being infected with diseases and pest invasion;
  • protect young bushes from freezing in winter, by covering them with special materials that let in moisture and air, which will ensure a normal microclimate.
Competent care will have a favorable effect on crop growth and the development of the vineyard as a whole.

Breeding methods

The plant is well rooted and takes root. Jupiter can be multiplied:

Rooted cuttings or grafted seedlings

Rooting grapes cuttings

This breeding method is good because bushes completely inherit all the technical characteristics of the variety. And the grafted specimens are distinguished by the most powerful growth force.

With graft stock

According to experienced winegrowers, excellent compatibility with Jupiter with rootstocks grapes Kober 5BB, C04 and Berlandieri XRiparia.

Layering from the mother bush

Laying grape slice for breeding

In this case, you need to use fruiting grapevine with strong, well-matured vines, which will serve as a material for breeding grapes.

Diseases and pests

The average resistance of Jupiter to disease. Therefore, oidium and mildew should be constantly fought, that is, regularly treated with special means from fungal diseases. Prevention needs to be started in early spring, when young leaves will form, with an average air temperature of 12̊ C, and continue until the fruit ripens.

The plant can be attacked by many pests, namely grape aphid, weevils, ticks, midges. In order for the vineyard not to become the center of a cluster of dangerous insects, protective procedures must be carried out in time. In the spring and autumn to clean up and burn the fallen leaves. Also inspect the bushes, and in identifying problems to resort to mechanical and chemical methods.

Grape Jupiter is of particular interest to winegrowers, due to the early term of ripening, attractive appearance of fruits, their harmonious taste, as well as resistance to adverse factors and climatic conditions.
