The article presents the results of the comparison of two methods for potato minitubers cultivation, namely: in summer-type greenhouses and in field under a covering material in the climate conditions of the Middle Volga, Russia. This assessment was undertaken in the breeding and seed center of Agrostar LLC. The objective of the work is to assess the economic efficiency of both technologies for potato minitubers cultivation and justify the possibility of using the best of them for implementation in the original seed production. The micro-plants for the study were obtained from the biotechnological laboratories of the Samara Scientific Research Institute of Agricultural Sciences and the seedgrowing farm Tsirulev E.P., Samara region. The results obtained indicate that the most effective method of growth potato minitubers is in field under a covering material. This work was carried out as part of a comprehensive scientific and technical project “Development of breeding and seed production of potatoes in the Samara region”. Russian and Western European cultivars were used in the study.

The article discusses the practical aspects of seed production of monoecious Ko noble planting. It is shown that the production of varietal seeds, maintenance of economically valuable traits, properties and preservation of biological purity of hemp varieties at a high level is possible only with a well-established seed production system. Long-term experimental data on the assessment of plants from 1-year breeding nurseries for the content of tetrahydrocannabinol (THC) by gas-liquid chromatography (GC) are presented. Techniques that ensure the formation of high varietal and sowing qualities as well as yield properties of seed material are considered.

The microtoponymy of the Middle Volga region is of particular interest to the author because of the polyethnic and multilingual environment. It is a region of cohabitation of Slavic, Turkic and Finno-Ugric population groups. The facts of ethnocultural interaction are revealed in substrate microtoponyms, which often have Turkic origins.There are also Finno-Volga substratum elements.Many of them were reinterpreted in Russian language.
