The hybrid variety Oscar is popular with Russian gardeners for a reason. This is a good grape, unpretentious in cultivation, while it has a high yield.
Breeding history
We must owe the appearance of Oscar to the amateur breeder A.V. Karpushev.
Geography of distribution
Distributed over most of our country.
Description
If we talk about the purpose of grapes, then this is definitely a table view.
The flowers are functionally feminine on the bushes. The plant has an above average vigor. Up to 90% of the formed fruit-bearing shoots are formed.
About 3 inflorescences appear on each shoot. Standardization for this variety is required.
Ripening period
From the moment the buds are formed on the plant, 110-115 days pass before the harvest. Oscar belongs to the early-medium varieties in terms of ripening. You can pick ripe, tasty berries in mid-August.
Bunches
Cylindro-conical clusters weigh an average of 479 grams. Their density also depends on the quality of pollination.
One of the Oscars' advantages is the absence of peas.
Berries
The berries have an attractive raspberry color. The skin is of medium density. Oscar can also be singled out for the fleshy pulp.
The fruits are papillary or elongated-oval in shape. Each fruit weighs 10.9 grams. If we talk about the size, then it is 50 mm, so they are considered large.
There is a waxy coating on the fruits.
Taste
The grapes have an amazing harmonious taste. Sugar in fruits 180 g / dm³.
Yield
Oscar is a high-yielding variety.
Growing features
Precisely because Oscar develops a female type of flower, he responds well to gibberellic acid. When applied, the fruits lengthen a little, the thickness becomes more uniform, the bone disappears, and the ripening period is shortened.
The main advice to the gardener is to keep the proportion correctly. If this rule is neglected, then the positive effect of the use of acid will be replaced by a negative one: the berries crumble, the stalk hardens. Enough 20 mg per liter.
Landing
Planting is done in the same way as when planting any other grapes. The size of the pit is 1x1 meter, the depth of immersion of the seedling is 30 cm. You can put fertilizers on the bottom of the pit, they will help the plant in the first year of life.
Drainage is necessarily formed if the groundwater is close to the surface. Oscar does not like excess moisture, like most other grape varieties.
Pollination
Due to the fact that only the female type of flower is formed on the Oscar vine, pollination is required.
Pruning
Pruning is an important step in plant care. From 6 to 8 buds are left for the shoot.If the variety is overloaded, then the ripening period increases, the berries lose their presentation, this is manifested by a poor set of colors.
Watering
In case of severe drought, the grapes are watered regularly. But it is worth giving up excessive soil moisture during the period when the berries are ripening. The consequence of waterlogging will be cracking of the fruit. When the berries are already ripe, they are no longer afraid of a large amount of water.
Top dressing
In the spring, nitrogen fertilizers are applied, they help the plant to gain greens. After harvesting the fruits, fertilizer with phosphorus and potassium is applied to the soil.
Frost resistance and the need for shelter
Oscar's frost resistance is -22 degrees Celsius. But he still needs shelter. You can use improvised materials, for example, spruce branches. It will protect you from frost and retain the required amount of moisture in the soil.
Diseases and pests
Despite the fact that the variety has resistance to pests and diseases at the level of 3.5-4 points, professionals always advise to carry out preventive treatment of bushes in spring with slaked lime or copper sulfate.
If a grape is exposed to any disease or insect, this always affects its appearance.
Storage
Even if the bunches of grapes are not picked immediately, they hang on the bushes for a long time and will not lose their presentation. The fruits are well transported and stored in the warehouse, subject to the temperature regime.
