The object is a specialized breeding material intended for the creation of hybrids. The line was obtained as a result of work to improve characteristics, including early flowering, reduced plant height, and changes in oil content.
Due to its status as a breeding line, standard agronomic characteristics such as yield or disease resistance are not published for it. The genetic properties of the line are transferred to the final hybrid, for which it serves as a parent form.
