Among modern varieties of raspberries, a special place is occupied by a Polish selection. Development began in 1979 at an experimental station in Brzezna. Since then, a number of excellent varieties have been developed, which are in demand in many countries of the world. The early maturing Radzieva variety (Radziejowa or Rubus daeus Radzieva) is considered a promising novelty.
Breeding history of the variety
It was bred by the efforts of the renowned breeder Jan Danek in collaboration with Doctor of Biology Agnieszka Orzel at the Experimental Chair of the Institute of Horticulture in Brzezno. In addition to Radziev, the result of their joint work was the popular varieties Sokolitsa, Poem, Polonez. In 2010, the variety was included in the National Register of Fruit Crops in Poland. Radziev was obtained by crossing the Polish Laszka, Polana and the British Malling Promise raspberry. The variety owes its name to Mount Radzeev in the Beskydy Mountains, located in the famous Carpathians.
Description of the variety
Radzieva is an ultra-early, high-yielding, not too winter-hardy, but disease-resistant, multi-purpose raspberry variety with large bright red fruits of a dessert taste.
Ripening terms
Fruiting of the variety starts early, in early to mid-June (slightly earlier than the Lyachka variety) and stretches until the beginning of autumn. If recurrent frosts occur in April, then the buds may freeze: bald spots form on the affected shoots, and a small berry grows. The earliest and most flawless harvest can be harvested when grown in a greenhouse.
Growing regions
In Poland, the variety has begun to be actively cultivated on commercial open planations and in greenhouses. Well Radzieva grows in Europe, Ukraine, Belarus, the Baltic countries. There are still few reviews from Russian gardeners. Apparently, Radzieva will feel good in the southern regions (but not arid), in the middle zone, in the Urals. A large Siberian nursery VASKHNIL successfully grows this variety in greenhouses and offers seedlings for sale all season: from April to October.
Yield
Radziev gives a rich harvest of almost one-dimensional fruits of excellent presentation. You can collect 3-6 kg of berries from a bush. One fruit branch (lateral) contains about a dozen berries. Gathering raspberries is comfortable: Radziev has few thorns, they are short and soft. High transportability: raspberries do not flow and do not lose their color brightness during transportation and storage.
Berries and their taste
The berries of the Radziev variety are large, heavy (average weight 6-8 g, sometimes up to 10 g), the color varies from dark pink to deep red-raspberry, with almost no shine. The shape is conical, elongated. The pulp is fragrant, juicy. The berry is dry and dense, when ripe, it easily breaks off from the stalks, does not crumble at all into drupes. The taste is sweet and sour, with a high sugar content. Suitable for fresh consumption, baking, for various preparations and freezing.
Growing features
It thrives best in temperate climates. Many farmers in the south of Russia and Ukraine note that he does not like excessive heat: in such conditions, the growth of replacement shoots slows down. In terms of agricultural technology, the variety is sensitive to feeding - nitrogen and mineral (phosphorus, potash) fertilizers should be applied regularly. Usually the bushes of this raspberry are medium-sized, 120-130 cm with erect strong branches, therefore they stand without support, but their height can reach 160-190 cm, then a garter to the trellises is needed.
The variety is distinguished by an underdeveloped root system, which must be protected by mulching and protected from both drying out and decay.
Site selection and soil preparation
Saplings are planted in March or October. For a plantation, it is recommended to choose a flat or with a slight slope, sunny, calm area. Radzieva loves light fertile soils: loam or sandy loam. With tape planting, the holes are made at a distance of 50-70 cm, with bush planting, they are kept about 1.3 m between plants and 2.5 m between rows. The soil under the seedlings must be loosened, fertilized with organic matter, ash, be sure to add mulch.
Pruning
For stable fruiting and disease prevention, thinning and sanitary pruning is carried out regularly, in autumn and spring.
Frost resistance and preparation for winter
Moderate winter hardiness, according to tests, it is declared down to -35 ° C. To exclude freezing, it is necessary to prepare the plant for wintering by bending the shoots to the ground and covering it with agrotex.
Diseases and pests
The variety perfectly resists the main viral and fungal diseases of fruit crops. Root decay is possible with excessive soil moisture. Breeders claim high resistance to pest infestation. But, according to reviews, this raspberry is often exposed to tick attacks.
Unfortunately, raspberries, like other plants, do not bypass various diseases and pests. Only armed with the knowledge and the necessary means for this, you can cope with such troubles. To help the plant, it is very important to be able to recognize the disease in time and begin timely treatment.
Reproduction
The most affordable ways to reproduce Radziev are by dividing the parent bush and young shoots. In the spring, after carefully digging up and separating the growth with a lump of soil, it is planted in a place prepared in advance.
