The inheritance of fatty acid composition in F1 seed and of their progenies (F2) is studied.It is established that the oil quality of F1 seeds is determined by the joint action of the embryo genome and the female parent genome, but in different combinations a specific degree of expression of those factors is observed.In F2 progeny of F1 and RF1 seeds the accumulation of diffcrent fatty acids is determined by the sced genome and because of that the composition of the oil is identical.In some crosses a partial dominance is observed of the low and high content of linoleic, oleic and palmitic acids.In all crosses the stearic acid content super-dominates toward the parent with a higher value.
