The diversity of climatic and extreme weather conditions in Mongolia requires the presence of a wide range of varieties in the production that differ in their biological and economic characteristics. The Siberian selectionists created grain crops varieties that are drought-resistant, well adapted to the sharply continental climate, with good baking qualities, capable of forming a crop in extreme conditions. According to the contract between Krasnoyarsk state agrarian university (Russia) and “ShinjeAmzhilt” company (Mongolia), the research on the adaptive capacity and elements of cultivation technology of the Siberian selection wheat was conducted on the land of “ShinjeAmzhilt” company in order to develop recommendations aimed at increasing the productivity of agrocenosis. The objects of the research were the varieties of Siberian selection wheat: Novosibirskaya-15, Novosibirskaya-31, Kantegirskaya-89 and varieties Selenge and Tobolskaya, cultivated in “ShinjeAmzhilt” company. Records and observations of wheat plants were carried out during the vegetation season using generally accepted techniques and existing state standards. Statistical processing of the obtained data was carried out by the method of dispersion and correlation analysis. The obtained results allow to conclude that despite the lack of moisture during the vegetation season, the greatest biological yield was formed by the Siberian variety of selection Novosibirskaya-31, and this data emphasize the adaptive potential of the variety and the ability to resist adverse factors.
