The object is not an independent variety or hybrid for mass field cultivation. This inbred line is used by breeders as a parental component in the creation of new high-yielding hybrids.
The line possesses genetic resistance to five races of Orobanche cumana, including races A, B, C, D and E. Characteristics such as plant height, maturity group, or commercial quality indicators are not applicable to this line, as they manifest only in derivative hybrids.
