Oil flax was grown on gray forest soils of the Middle Urals in the period 2012-2020. The purpose of the research was to identify changes in the yield structure of various oil flax varieties and its productivity, depending on the growing conditions. The research used the method of field experience and statistical processing of experimental data. It was found that the conditions of the year of growing oil flax had a noticeable effect on the number of formed capsules on the plant, seeds in one capsule and the mass of 1000 seeds. Small seeds of all varieties were formed in the conditions of warm and dry 2012, and the largest seeds were obtained in cool and wet 2015. The average yield of oil flax seeds was 1.90-2.14 t/ha, the maximum yield was 2.88 t/ha, provided by the Ural variety in 2017. The yield variability level by 77.7 % was determined by environmental conditions, the influence of genotypes caused 6.6% of yield variation, and the interaction of genotype x environment - 14.9 %.
