This paper presents the results for the temperature and amount of precipitation per decade, based on HMS Omsk for the period 2009–2013. Thus, agro-climatic conditions in the years of experiments allowed a more comprehensive 49 50 and reliable assessment grades of flax oil. Before presented the results of ecological plasticity linseed cultivars. Adaptive properties assessments aligned with the method proposed S.A. Eberhart, W.A. Russell. The method is based on calculation of two parameters: coefficient of linear regression and standard deviation from the regression line dispersion. The regression coefficient provides a measure of the plasticity of the variety in the genetic sense. The second characterizes the stability of the variety in different environmental conditions. It is shown that the varieties Sokol, Isilkulsky, North, Surprise have relatively high productivity and responsiveness to growing conditions and however low stability. These varieties are recommended for use as initial material in selection on the high productivity and fertility.
