The hybrid belongs to the oil-type use category. In studies from the late 90s, seeds of this variety demonstrated an oil content of 42–43%.
This hybrid was historically used as a standard in field trials in a number of European regions. Due to the development of breeding and the emergence of new races of downy mildew, it has given way to modern types of hybrids that possess increased resistance to diseases.
