• Abstract The study of the genetic characteristics of the reaction of plants to changes in environmental conditions makes it possible to more effectively use the achievements of breeding. In the conditions of the open forest-steppe of the Krasnoyarsk Territory in 2019 - 2020, a study of the yield of winter rye was carried out on a site with a low nitrogen content against two backgrounds: without fertilizers (control) and with fertilization. The object of the research is the varieties included in the State Register for the East Siberian region Yeniseyka (standard), Sinilga, Krasnoyarskaya universal and the Arga variety undergoing state testing. In the dry 2019 year, the average yield in the control variant was 27.5 c(centner) / ha, the increase from fertilization was 8.2 c / ha. In conditions of excessive moisture in 2020, it was respectively - 32.7 c / ha and 13.6 c / ha. The response of varieties to background changes of mineral nutrition was different. The most responsive to fertilization was the Arga variety, the most stable was the Sinilga variety. Krasnoyarskaya universal and Arga surpassed Yeniseyka and Sinilga in average yield by 2.3-2.7 centners / ha and were more resistant to lodging. Arga had an advantage in productivity with a sufficient supply of nutrients, the Krasnoyarsk universal was characterized by greater stability and less response to agrotechnical background changes.
