Primocane raspberry cultivars for industrial cultivation in Russia
Since 1972 an extensive breeding program for primocane fruiting raspberries has been underway at the Kokino experimental station of State Budgetary Institution of the Science All-Russian Horticultural Institute for Breeding, Agrotechnology and Nursery. Cultivars developed for outdoor fruiting in this program are distinguished by their adaptation to high temperatures, a short growing season, and by their early production, upright growth habit, large fruit size and long hanging ability on the plant (up to 5 days) between harvests without significant deterioration of fruit quality. In this paper information on the commercial and biological characteristics of some raspberry cultivars bred at this location is provided. The cultivar Atlant has medium fruit size (5.0 to 5.5 g), and high quality berries. It does not require trellis installation, is resistant to gray mold of fruits, suitable for machine harvesting, long-term storage and transportation. The cultivars Eurasia and Penguin are characterized by very early and even ripening, erect growth habit, firm fruits, and easy separation of fruits from receptacles. The cultivar Zhar-ptitsa has high productivity (ranging from 18 to 20 t ha‑1), is resistant to fungus diseases (Gloeosporium venetum, Leptosphaeria coniothyrium, Didymella applanata, Sphaerotheca mors-uvae) and the fruits have excellent dessert taste. The cultivar Poklon Kazakovu is distinguished by large fruit size, excellent fresh market taste, distinctive raspberry aroma and attractive fresh market fruit appearance. The cultivar Medvezhonok is distinguished by sustainable high productivity (ranging from 16 to 18 t ha‑1), early ripening, resistance to major fungus and viral diseases as well as large and firm fruits. These cultivars are suitable for the commercial cultivation including machine harvesting.
