Abstract

A paper contains materials on the study of bog bilberry in the conditions of Central Yakutia, which are presented in the paper. In the species, there is a variability in the morphological, endogenous, individual, geographical and ecological variability of generative and vegetative organs, as well as phenological development. Among the following traits, there was greatest variability: number of berries per bush (30.1%), and size of the branch (leaf blade length and thickness) 30.9% and 29.3%, respectively. Less variables were berry weight (15%) and height of fruit-bearing bushes (14.9%), but they were not much different from other variable traits. Among the traits that have been studied, the taiga zone of South Yakutia can be considered an ecological optimum for V.uliginosum due to the manifestation in most of the studied traits. Bog bilberry in the conditions of Central Yakutia requires more thorough study and brand-new agrotechnical cultivation methods due to the slow entry of plants into the generative stage of development. The introduction is required for an improved approach to plant production, as well as new agrotechnical techniques that are adapted to support the slow entry of plants into the generative stage of development.
