The RHA SP line is classified as a fertility restorer line and is used exclusively for breeding purposes as a parental component in the creation of hybrids.
Genetic studies confirm the line's resistance to Orobanche cumana race E. Detailed agronomic characteristics, such as plant height, maturity group, or oil content indicators, are not available in open publications.
