Winter hardiness of remontant raspberry under field and controlled conditions

The development of fruit farming, an important branch of agriculture, is impossible without the introduction of new crops and new varieties. Replanted raspberries are a new crop for Siberia. Increased interest in it is determined by its biochemical composition, high productivity, and long fruit-bearing. Large-fruited varieties of European selection of summer fruiting do not always winter in the best way. We were interested in the possibility of expanding the potential of the studied varieties of remontant raspberry in the conditions of the Siberian climate, using it not only in an annual mowed crop but also to find out how realistic it is to get a yield from two-year shoots of remontant raspberry. For this purpose, the winter hardiness of floricans of remontant raspberry varieties was characterized. The most frost-resistant remontant raspberry varieties were identified according to the results of research. Critical negative temperature for all studied varieties and forms of remontant raspberry was determined.
