The research was conducted in selection crop rotation of Krasnoyarsk Research Agricultural Institute in Krasnoyarsk forest-steppe zone of East Siberian region in 2013-2016. The authors observed strongly opposite Agrometeorological conditions in the vegetation periods of research periods: 2013 and 2014 were rather humid where hydrothermal index was 2.20 and 2.11); 2015 was characterized by insufficient humidity (1,21); humidity in 2016 was equal to 1,59. The paper highlights the specimens that are of practical significance. Abalak, E-88-5893 and T-66-3194 contain higher amount of gross protein (5,00-5,10 t/ha); Kedr, Buyan , Olenek, T-66-3194, U-49-3795, U-273593,U-30-3624 and F-68-4721 contain higher number of grains in the main spike (19,1-22,4); Kedr, BIOM and TS-29-5047 are significant for their mass of 1000 grains (47,5-49,6); higher crop yield capacity was observed in Abalak, E-88-5893, T-66-3194,U-49-3795, F-68-4721 (significant increase to the standard 3.3 to 5.6 C/ha, or 8.5 to 14.5%); environmental stability (St2) was typical for E- 88-5893, T-66-3194,U-27-3593 and U-30-3624; response to better cultivating conditions was observed in Kedr (1.14), Olenek (1.38), Abalak (1.10), U-49-3795 (1.09) and F-68-4721 ( 1.09); General adaptive ability is typical for – Abalak (4,05), E-88-5863 (3,63) and T-66-3194 (4,33); specific adaptive capacity was observed in significant Kedr, Vulkan, Abalak, Olenek, U-49-3795 and F - 68-4721; genotype stability (Sgi) – E-88-5893, T-66-3194, U-27-3593, U-30-3624; selection value of the genotype (SGI) is typical for Vulkan (23,20), Olenek (20,30), Abalak (22,11), E-88-5893 (21,84), T-66-3194 (22,21), U-27-3593 (20,00), U-49-3795 (21,10) and F-68-4721 (20,90), which confirms their higher adaptive properties in extreme conditions of Eastern Siberia. The researchers outline efficient lines: E-88-5893 (Emelya) and T-66-3194 (Takmak).
