Сравнение современных сортов малины, выращиваемых по системе Long Cane

Raspberry fruits (Rubus idaeus L.) are a unique natural source of a whole balanced in composition complex of nutritious and biologically active substances that attracts the attention of the whole world. Raspberries contain vitamins, minerals (potassium (K), calcium (Ca), iron (Fe), zinc (Zn) and manganese (Mn)), unsaturated fat acids, sugars, proteins and polyphenols. In addition, raspberries have a high antioxidant potential, due to the increased accumulation of ascorbic, ellagic, folic acids and anthocyanins. That is why raspberry fruits have antioxidant, anti-inflammatory, chemo-preventive and antimicrobial properties, which significantly affect the human vital processes.

Raspberries varieties (Rubus idaeus L.) are divided into summer (biennial-fruiting) and remontant (primocane-fruiting). Basically, varieties that are used for container growing of long cane in high tunnels are summer (biennial-fruiting), their shoots are formed during one growing season, then plants are removed to frigo-storage. The difference between traditional and remontant varieties is that remontant varieties’ blooming and bearing are not related with day length and temperature. In traditional varieties the dormant period begins after the initiation of flowering.

According to FAO data for 2020, the area of raspberry plantations in the world was 112 167 hectares, and the yield was 895 771 tons, while in 2019 — 841 351 tons were obtained from an area of 122 195 hectares. That indicates the dynamics of berry producing growth despite the decrease in areas. The leading countries raspberries producing are the Russian Federation (151 738 tons), Serbia (92 514 tons), Poland (84 674 tons) and the USA (81 865 tons). In Russia, to preserve the current industrial area (2412.2 ha), the minimum annual need in raspberry planting material is 2 560 643 seedlings.
