ANALYSIS OF THE CORRELATION OF PRODUCTIVITY AND ADAPTABILITY OF BARLEY VARIETIES
The purpose of the study is to determine the correlation of adaptive parameters of spring barley varieties with productivity and the main indicators of grain quality from 2011 to 2019 in the conditions of the southern forest-steppe of Western Siberia. Increased plasticity of barley varieties did not significantly affect the yield and quality of grain (r = 0.109 and 0.232). With increasing stability of varieties, the content of starch (r = 0.429) and raw fat in the grain (r = 0.656) increased; the yield (r = -0,204), the protein content (r = -0,399) and the film content of the grain (r = -0,447) decreased.
