The aim of the research was to study introduced cultivars of raspberries on economic and biological characteristics and selection of adapted to the conditions of the Crimea, high-yielding, winter-hardy, disease- resistant cultivars with high taste and commercial qualities of berries. The article presents the results of a study of seven raspberry cultivars (Glen Ample, Cowichan, Laszka, Marianuska, Perseya, Polka, Phenomen) for agronomic characteristics: yield, disease resistance, average weight, quality and biochemical composition of berries. Control - Balsam cultivar, recognized in the Crimea. The data obtained allowed to distinguish the following cultivars: on the basis of large fruit size (3.0-4.0 g) Phenomen, Laszka, Glen Ample, Marianuska, Cowichan; high yield (0.322 - 0.393 kg/shoot) Laszka, Marianuska, Perseya; good taste of fruits (4.5 - 4.9 points) Cowichan, Marianuska, Perseya, Polka; high content of ascorbic acid (47.6 - 61.7 mg/100g) Glen Ample, Marianuska, Perseya; the high content of soluble solids (15.3 - 17.7%) Laszka, Marianuska, Polka, Phenomen, Cowichan. Over the years of research, all raspberry plants had a healthy appearance; chemical treatments on the experimental site were not used. The introduction of promising cultivars of raspberries will significantly improve the assortment of culture in the Crimea, increase the production of berry products. The best cultivars chosen for valuable characters can be used in breeding.
