Abstract

The possibility of using remontant varieties adapted to the climate of the northern regions will allow solving the problem of overwintering raspberries, both in amateur and industrial plantings. Obtaining primary experimental data on the requirements for soil and climatic conditions, resistance to diseases and pests, growth characteristics and individual development in five remontant raspberry varieties is the first stage in the development of guidelines for the formation of remontant raspberry agrophytocenoses in the Komi Republic. The collection nursery of remontant forms of raspberries of the Institute of Agrobiotechnology of the Federal Research Center of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences was founded in 2018 and is represented by 5 varieties: Ruby necklace; Firebird, Elegant, Orange miracle, Hercules (St.). The studies were carried out according to the provisions of the standard method of field experiment during the growing seasons of 2018-2019. Agrometeorological conditions in 2018 were favorable for raspberry plants, in contrast to 2019. The unfavorable balance of heat and humidity during the growing season of 2019 caused the end of the development of remontant raspberries at the stage of vegetative growth (Hercules variety) or the flowering phase (4 varieties). Variety Orange miracle in the conditions of the Komi Republic is more susceptible to the risks of developing mycoses and damage by shoot gall midge. In the standard variety Hercules, despite the good vegetative growth of shoots in both years, a massive transition of plants to the ripening of berries was not noted. According to the results of two years of research, the varieties Ruby Necklace and Elegant showed good results in the formation of a certain number of shoots, resistance to pests and diseases, and the general condition of plants at the end of flowering.
