Grapes "Rumba" is one of the relatively new hybrid forms obtained by the Russian breeder Kapelyushny V.U. as a result of work on crossing the variety "ZOS-1", or "Enthusiasm red", with the variety "Charrel".

Grade characteristics

Grapes "Rumba" from amateur selection are among the promising table forms with a very early ripening period, which takes from 95 to 100 days. Fully ripened berries can be harvested in early August.

Biological description

The hybrid form (GF) of Rumba grapes forms very strong and well-developed, rapidly growing bushes. The average length of annual shoots can exceed 5 m. At the full fruiting phase, the bushes of this GF go a couple of years after planting.

The grapes are quite large and massive, have a cylindrical shape. The average weight of a ripened grape brush can vary from 0.8 to 1.0 kg. Quite often, the mass of a bunch reaches 1.5 kg. The brush has a medium density structure and an attractive appearance.

Technical characteristics of berries

Grapes "Rumba" refers to the table grades of pink grapes demanded by consumers. The average weight of large ripe berries is from 8 to 10 g. The standard size of the berry is 3.2 x 2.4 cm. The shape of the berry can be either oval or elongated-ovate. When fully ripened, the berries acquire a very pleasant, pale pink color.

The taste is harmonious, with a slight tinge of a light muscat aroma. The flesh of a ripe berry is fleshy and quite juicy, covered with a medium-thick skin. The sugar content of the juice varies from 20% to 23%. The acidity of the juice does not exceed 5-6 g / l.

Grade Benefits

"Rumba" has all the advantages that are inherent in the hybrid form of the parent line used in the derivation:

  • frost resistance of fruit buds reaches -24 C;
  • high and very stable productivity;
  • resistance to damage by the main and most common diseases - about 2.5 points;
  • very high transportability;
  • the ability of cuttings to quick and easy rooting;
  • fast and friendly ripening;
  • It has excellent appearance and taste.

Disadvantages can be attributed the tendency of the berries to chop as a result of overloading the vine with the crop. When cultivated in climatic conditions with cold and long winters, sheltering of the vine is required.

Landing rules

Grapes under the sonorous name of "Rumba" is not demanding on the quality of the composition of the soil, therefore it is allowed to plant seedlings on insufficiently fertile soils in compliance with the following requirements:

  • two weeks before digging trenches for planting, it is necessary to deeply forge the soil and bring a bucket of humus to each square meter of area;
  • the distance between individual pits for landing should be about 3 m, which will ensure the full development and nutrition of the root system;
  • standard pit dimensions - 0.8x0.8x0.8 m;
  • with a high location of groundwater, it is necessary to lay the drainage layer of fine stone or gravel;
  • in the center of the pit, it is imperative to install a support for the vertical arrangement of the vine.

Prepared for planting seedlings should be healthy and well developed. The day before planting, anti-aging pruning of the roots should be carried out and the root system should be soaked in water with the “heteroauxin” agent. A young shoot should have at least 4 eyes, and the standard growth length should be from 15 to 20 cm.

Care Features

Grapes "Rumba" is very responsive to compliance with all care activities. Proper agricultural technology allows you to increase productivity and improve the commercial quality of berries.

Watering and feeding

Watering bushes gf grapes "Rumba" should not be excessive. The first and most plentiful watering is carried out immediately after planting seedlings. The average water consumption is about two buckets per bush. Watering of the same volume is carried out after pruning the bushes and at the stage of active vegetation.

When apiaries appear on shoots, irrigation should be stopped almost completely. Before shelter for the winter period and at the beginning of the growing season, moisture-charging irrigation is carried out, which stimulate the quick adaptation of the plant to changing weather conditions.

Fertilizing with complex fertilizers is carried out no more than once every three years. It is recommended to combine the application of liquid fertilizers with irrigation measures. In addition, once every 2–3 years, organic fertilizers are required under the bushes. The best option is to use a solution of bird droppings, as well as humus or compost, which can be mulched.

Before flowering, top dressing may contain components such as:

  • superphosphate,
  • potassium salt,
  • ammonium nitrate.

After flowering of the vineyard, nitrogen fertilizers do not need to be applied. Before shelter in the winter, it is recommended to feed the bushes with potassium salt.

Cropping and shaping

Grapes "Rumba" forms quite powerful bushes, which requires careful attention to pruning. Besides, a plant of this hybrid form is prone to overloading and crushing berries. Therefore, the standard optimal load on each grape bush should not exceed 30-35 eyes.

Pruning fruiting vines should be carried out for 8-10 eyes. With proper formation, the maturation of the vine exceeds 2/3 of its length, which is a very high indicator for gf.

Reviews of winegrowers

The hybrid form of grapes called "Rumba" is most often characterized by gardeners and winegrowers on the positive side. Many note such advantages of this form as super-early ripening, excellent presentation and color, medium-sized and half-loose clusters in structure, the absence of sunburn on berries, excellent ripening of the vine, and excellent rooting.

How to grow grapes

A very important advantage of Rumba grapes is that most growers consider resistance to the most dangerous diseases for grape bushes and the absence of damage on berries from wasps and hornets. Even signal brushes look very attractive and appetizing.

A large number of advantages, as well as the ability to cultivate a hybrid in the southern regions without shelters, allows this grape to be considered worthy and promising for home cultivation.
