The North of the Far East is a geographically and economically isolated zone with extreme agro-climatic conditions, which leads to the need to develop its own food base. The harsh conditions of the northern territories dictate the careful selection of a specific assortment of crops, both for the needs of the population and for the purposes of animal husbandry. Annual and perennial forage crops of non-district origin, currently used in peasant farms in the conditions of the Magadan region, have a low adaptation to the growing environment, expressed in a decrease in the viability of seeds, heterogeneity of seedlings, elongation of the phases of vegetation of plants, which negatively affects the yield and quality of green mass and hay. An alternative option is the use of perennial grasses of the native northern flora, in particular arctagrostis broadleaf, which grows wild in the coastal and continental regions of the north-east of Russia. This species has been cultivated since 1971 and is the main source of raw material for breeding, currently conducted by the Magadan Research Institute of Agriculture. By 2022, as a result of long-term selections (positive and negative), seven samples have been identified that have the best indicators for biomorphological and economically valuable characteristics, biochemical composition, yield of green mass and hay, distinguished by the stability of parameters throughout the entire period of research and are of great interest for further breeding work.
