Dynamics of oil content and fatty acids composition variation in soybean cultivars of domestic breeding

This paper presents the study of vegetative characteristics and chemical composition of soybean cultivars of domestic breeding. The data on yield, protein content, oil content and fatty acids composition of cultivars studied are presented. The conformity of lower oil content in seeds with higher level of protein accumulation is established.Some minor cultivar-dependent fluctuations in the fatty acids ratio along with harvest year dependence have been observed. The greatest fluctuations have been observed in the concentrations of oleic and linoleic acids. The data obtained indicate the presence of cultivar-dependent variations in the fatty acids composition of the oils studied due to genotypic features. However, despite the variations, the cultivars studied demonstrate stability of fatty acids composition and are recommended for further breeding.
