Grape growers are trying to acquire varieties that differ in taste, yield, quick ripening and disease resistance. But some growers are willing to give up on a variety with a lot of seeds.
Seedless varieties are referred to as raisins, and this is exactly what the Jupiter grape is. The features of the variety, characteristics, rules of cultivation and care will be discussed in the article. Photos, videos and reviews are given for clarity.
History reference
The creators of the Jupiter raisins table grapes are American scientists John R. Clark, James N. Moore from the University of Arkansas, USA. To obtain a hybrid, the varieties Arkansas Selection 1258 x Arkansas Selection 1762 were used as parents. The grapes of the new variety were created relatively recently, in the year 98 of the last century. American breeding raisins came to Russia and Ukraine 12 years later.
In the interspecific hybrid variety Jupiter there are no seeds, the grapes have a lot of advantages, they retain their presentation during transportation. The variety is suitable not only for industrial cultivation. Since there are no particular difficulties in caring for the vine, the grapes of the quiche mish Jupiter can be planted in private plots.
Description
A description of Jupiter grapes from the USA, as well as some photos and reviews of gardeners, are necessary so that our readers can understand what this hybrid is.
Features of the bush
The hybrid variety of raisins Jupiter USA is represented by vigorous or medium-sized bushes. Reproduces excellently by rooting cuttings. Fruiting begins two or three years after planting.
The vine of the Jupiter raisin variety is reddish brown or light brown, not too high. The decorativeness of the bush is appreciated by lovers of landscape design. Look at the photo, what kind of composition can be created on a plot of grapevine.
The leaves are large, rich green. They have three blades with a weak dissection. Up to 5 inflorescences can form on one shoot. American variety of raisins Jupiter - the owner of bisexual flowers, does not require additional pollination.
Bunches
The Jupiter variety stands out for its large clusters (this can be clearly seen in the photo). Their weight ranges from 250-500 grams. The bunches of the variety are decorative, have the shape of a cone or cylinder, moderately winged. Looseness of groves is average.
The decorativeness of the bunches is given by the different colors of the berries at the ripening stage. On one groove, you can simultaneously see green-pink, deep pink, red and dark blue fruits of Jupiter raisins.
Berries
Ovate or oblong-oval fruits are large, each from 5 to 7 grams. The tip of the grape is pointed. In technical maturity, the fruits are dark blue with a clearly visible matt bloom. You can estimate the size of the berries of the Jupiter kishmish variety from the photo, where the fruits are compared with a five-ruble coin.
Jupiter's flesh is juicy, dense, even crunchy. According to gardeners, the variety has an isable nutmeg tone in its taste. This is not surprising, because the grapes are obtained from crossing Isabella varieties.
The Jupiter grape, created by American breeders, belongs to raisins, so there are no seeds in them. Although rudiments are sometimes found, they are very soft.
Moderately sweet grapes are covered with a thin, but rather dense skin, wasps during ripening cannot damage it. In addition, they do not crack both on the bushes and during transportation.
Kishmish Jupiter from American breeders, gardener opinion:
The only thing that will depress gardeners (judging by the reviews), and we will not keep silent about this in the description - the shedding of berries. Therefore, it is advisable not to allow overripening of Jupiter grapes in order not to lose the harvest.
Characteristic
- The raisin grape Jupiter USA is a seedless table variety. Differs in early ripening of bunches - 110-125 days. The high yield of the variety is achieved due to the self-pollination of bisexual flowers, which help to pollinate neighboring grape bushes of other varieties.
- Due to the average mass of the bunch, the Jupiter variety does not require load rationing. You can leave up to 40 eyes on the vine. One hectare of Jupiter raisins, with proper care, can consistently yield up to 250 quintals of sweet grapes with a nutmeg flavor.
- The Jupiter USA grape variety belongs to frost-resistant plants, which allows gardeners to cultivate it in areas of risky farming. Withstands a variety of temperatures down to -29 degrees with light shelter. In the northern regions, where the mercury column falls below the specified level of winter hardiness, reliable insulation of grape bushes will be required. If the vine is frozen in winter (which is often written in reviews by newbies), it does not need to be uprooted, since the Jupiter variety has excellent survival, recovery occurs quickly.
- The popularity of US raisins grapes is added by high transportability: even when transported over long distances, the presentation remains at its height.
- The harvested Jupiter grapes are stored for several months.
As you can see, the American hybrid has a lot of positive qualities, although there are still disadvantages:
- The incidence of fungal diseases is average. More often it is oidium, mildew, gray rot. But timely treatment of grapes with drugs reduces the damage to leaves and fruits.
- Although it would be wrong to call this a disadvantage, it is precisely the small-sized bunches that often become the reason for the rejection of Jupiter grapes.
- And of course, the fall of berries from overripe bunches.
Reproduction methods
The hybrid grape Jupiter Kishmish, created in the USA, can be obtained in many ways, even in a regular flower pot:
- Rooted cuttings or grafted seedlings.
It should be noted that the ripening of grapes obtained from root-viable seedlings occurs earlier than the grafted specimens. - By grafting on the stock.
- Layers from the mother bush.
When rooting parental cuttings or when propagating by layering, it can be expected that the Jupiter raisin variety will retain the qualities and characteristics indicated in the description. But grafted seedlings can get the properties of a rootstock.
Experienced gardeners advise to use rootstocks "Kober 5BB", "С04" and "Berlandieri X Riparia" for obtaining seedlings of Jupiter raisins of the USA.
Landing features
You can plant Jupiter grape seedlings at any time, but autumn plantings are more successful. The main thing is not to wait for frost, otherwise the root system will not have time to recover and get stronger. For planting single bushes of the Jupiter variety, they dig a hole. If it is supposed to plant several copies, then it is better to prepare a trench, as in the photo below.
The grapes love fertile soil, in addition, drainage is laid on the bottom. The pit is filled up two weeks before planting. The seedling is soaked in water for several days. The landing pattern is shown in the photo below.
After planting, the soil around the seedling is mulched to retain moisture. Abundant watering is carried out after four days.
Grape care
There are no special rules for caring for the Jupiter variety, everything is traditional:
- Abundant watering, at least 15 liters for each bush after 3 days, if there is no precipitation. Moreover, it must be stopped 14 days before harvest. It is recommended to mulch the soil: and moisture evaporates more slowly, and weeds do not crush the plant. Experienced gardeners make the work easier by installing a drip irrigation system for planting grapes.
- In the spring, you need to apply nitrogen-containing fertilizers to build up green mass. Then you will need a complex top dressing of sulfate, potassium monophosphate, magnesium sulfate. Overfeeding the vine is not recommended, the fatty plant develops worse.
- And of course, you can't do without cropping. It is performed in the fall, shortening the shoots of the Jupiter variety by 6-8 eyes.
- To prevent grapes from getting sick, they carry out preventive treatment: twice before flowering and once after. Most often, experienced gardeners use Bordeaux mixture or Thanos or other fungicides.
- The last treatment is carried out with iron vitriol before laying the vine for the winter. As for this issue, the winter-hardy (withstand frost up to -29 degrees) grape raisins Jupiter, growing in the southern regions, does not need shelter. But the northerners need to take care of creating conditions for wintering.
