The aim of this work was to study the inheritance of the total tocopherol content (TTC) in backcrosses of sunflower breeding lines. Inheritance in the BC1 generation with a highly significant parent is carried out according to the type of intermediate and overdominance (h/d from -0.53 to 2.81), with low significance – according to the type of intermediate and negative overdominance (h/d from -0.59 to -1, 48). A significant positive correlation between the values of the recurrent parent and BC1, equal to 0.8, indicates the observed maternal effect. In the I1BC1 generation, positive and negative transgression was found.
