Evaluation of promising lines of spring rape of VNIIMK's breeding in different gradients of environmental conditions

Field experiments on the assessment of ecological plasticity of perspective lines of rapeseed of spring selection VNIIMK were carried out in 2016-2017 in Krasnodar region (Krasnodar and Armavir), Lipetsk region (Lipetsk) and Omsk region (Omsk). Weather conditions during the growing season of spring rapeseed in each year of research can be characterized as relatively favorable for all test points. The studied varieties of spring selection rapeseed VNIIMK belong to the early maturing group, which makes it possible to cultivate them in the more Northern regions of Russia. The new Ruyan variety (2.33 t/ha) stood out with the highest yield on average for years and points of study, and the highest oil content - high-oleic variety of rapeseed spring Amulet (49.2 %).
