Abstract
Cotton is a valuable crop for the Russian economy. Creation of the initial material for breeding work, as well as the introduction into production of high-yielding cotton varieties adapted to growing conditions are the main tasks set for Russian breeders. The study of agronomic traits of cotton varieties was carried out at Precaspian Agrarian Federal Scientific Center of the Russian Academy of Sciences, located in the north of the Astrakhan region, in 2017-2019. The research was performed in order to identify productivity potential, as well as to determine the adaptive capabilities to extreme climatic conditions of the Northern Caspian region. Cotton varieties were compared with the standard (AS-1). The results were processed according to methods of mathematical statistics. All varieties studied in the research had good indicators of agronomic traits. UZ-4 and Goliot varieties were characterized by the highest yield values - 3.0 and 2.6 t/ha, respectively.
