Delniwa

Delniwa is a variety characterized by vivid red, shiny fruits that maintain a unique flavor throughout the harvesting period. It is recommended for cultivation in open-field plantations. The shrub grows moderately strong, producing several stiff stems. Fruit-bearing occurs on this year’s stems for the larger part of the shoot. The yield is cumulative, with early harvesting (late July/early August). The yield is higher than that of the Polka variety (approximately 15 tons/ha). It produces large (4.5-7 g), vivid red, shiny, and firm fruits, primarily known for their excellent taste. The fruits store well, do not darken after harvest, and are resistant to transportation. These characteristics make Delniwa attractive for the fresh fruit market. The variety is also suitable for mechanical harvesting due to its upright stem growth, cumulative ripening, fruit exposure, and ease of detachment from the peduncle. Harvest efficiency is high (95%)—a large number of fruits suitable for simultaneous harvesting, with a low percentage of unripe fruits (1.6%). Additionally, the high extract content (12.5%) and positive results in freezing tests (a high percentage in the extra class and low drip values after thawing) make it interesting for processing. Delniwa is characterized by a high dry matter percentage, making it suitable for the production of high-quality lyophilized products. Among other red raspberry varieties, Delniwa stands out for its highest antioxidant capacity, measured by FRAP and DPPH indicators, high polyphenol content, and vitamins. It can be promoted as a superfruit that should be a permanent part of diets aiming to boost immunity against viruses and cancer. Cultivation recommendations: Plant rows should not exceed a width of 0.5 m (excessive density promotes shoot diseases). Maximum of 12-15 shoots per linear meter. 3.5-4 m spacing between rows. Protect against the development of pathogens (Didymella aplanata, Botrytis cinerea, Leptosphaeria, Phragmidium rubi-idaei). Delniwa is protected by exclusive EU rights No. 2017/3320.
