The grape variety has been used for centuries to make a popular delicacy - raisins.
Breeding history
The variety was developed at Davis Station in California in 1966. I managed to get it by crossing the other two species: Emperor x Pirovano 75. Only in the 80s. The century was entered on the register of America.
Geography of distribution
Today, summer residents and gardeners around the world grow grapes on their land. There are large plantations on the territory of our country. Most of all, the variety is concentrated in the south of Russia and in its central part.
The centenary can be found in the following regions:
- Krasnodar region;
- Voronezh region;
- Moscow region;
- Rostov;
- Yaroslavskaya oblast.
If we talk about where you can find the variety in the world, then these are most of the states of the United States, Australia, Chile, Italy and even South Africa.
Description
The century belongs to the table grape varieties. Bisexual flowers are formed on the plant.
Bushes quickly gain green mass, so the variety is classified as very vigorous.
The berries do not crumble, do not rot, which is why grapes have become so in demand. In winter, mature plants do not need to be covered.
Ripening period
Fruits ripen 115-125 days after the buds swell.
Bunches
The bunches grow large and conical in shape. The berries are on them in a moderate density relative to each other.
The mass of one bunch reaches 400-500 grams.
Berries
There is no seed inside the fruit. The grapes are ideal for making salads.
The fruits are white, the berries contain 130 g / dm³ of sugar. The acidity level is 6.
When you eat such grapes, you understand that the skin is thin, almost imperceptible. Inside each berry is crispy, juicy pulp. The weight of one fruit is 6 grams.
Taste
The Century grapes also fell in love for their harmonious taste, so they often become the main decoration of the table.
Yield
The plant belongs to high-yielding varieties.
Growing features
Cuttings of this variety have a high survival rate. By the fourth year, you can harvest. Ultra-compact and compressed vines in grafted grapes.
Be sure to thin out the bushes so as not to overload the plant. After banding, the immature part of the hand is removed.
The advantage of this species is that it is not prone to peas. Gibberellin is not required.
Landing
For planting, only the sunny side of the site is used. It is best when the rows run from south to north.
Cuttings are planted with equal success both in spring and in autumn. As with other varieties, the planting pit is prepared in advance. Dimensions - 80x80 cm, depth no more than a meter.
Fertilized soil is laid in the pit. Mix compost, humus and sand if the soil is clayey.
The mixture is compacted at the bottom and watered.
You can breed the Century through its own roots. Cuttings are recommended to be planted at a distance of 3 meters.
Pollination
Normalization by inflorescences is not required. The flowers are perfectly pollinated.
Pruning
The variety is cut at the rate of 10-12 eyes per vine. The buds located at the base are less fertile. If you remove them, then the yield will increase.
Watering
The first spring watering depends on how much snow fell in winter. If it is not enough, then they begin to add additional moisture from March, if a lot - from April.
Irrigation is carried out at the root. Moisture must be distributed and absorbed evenly.
Before flowering, a second watering is performed three weeks before flowering. When flowers appear, there is no need for this. Watering is resumed when berries appear.
Watering is stopped two weeks before harvesting. If this condition is not met, then the amount of sugar in the fruit is significantly reduced.
The last time is to irrigate the land after harvesting. When the soil cracks, it damages the root system of the bushes, which negatively affects the yield afterwards.
10 liters of water is enough for each bush, while it should not be cold.
Top dressing
When planting, fertilizers are introduced into the pit, they are enough for the first year. In the spring, you will need 50 grams of nitrogen, 40 grams of superphosphate and 30 grams of potassium salt.
Before flowers appear on the bushes (in 3 weeks), fertilizing is imperative. It consists of slurry. For 20 liters of water, 10 kilograms of manure is enough. This composition is then diluted fivefold. You will also need superphosphate in the amount of 20 grams and potassium salt - 15 grams.
In the period when the ovaries are already beginning to form, fertilizers must also be used: 50 grams of superphosphate and 250 grams of ash.
All fertilizers should be applied exclusively in liquid form. They do not water at the root, but pre-make grooves around the trunk. The distance from the stem is at least 50 centimeters, otherwise you can burn the roots.
Frost resistance and the need for shelter
In the Century, frost resistance is -21 ° C.
Diseases and pests
This grape has low resistance to fungal diseases.
Wasps do not eat it, therefore, it is not required to additionally cover the bunches.
Bushes are sprayed against insects as a prophylaxis. A biennial leafworm often damages grapes. Hitting under the bark, it destroys the plant.
Phyloxera is the main enemy that you have to fight. The insect is not only harmful, but also highly fertile. To avoid the problem, experts recommend making a stock for resistant varieties.
If a grape is exposed to any disease or insect, this always affects its appearance.
Storage
The grapes are well stored both on the vine and in favorable conditions in the warehouse. The longer the bunch lies, the brighter it becomes, and sugar accumulates in it.
It is worth removing the fruits from direct sunlight, otherwise brown spots will form on them.
