Variety description

10 August 2026

The line is a breeding tool, not a commercial variety for production planting. It is classified as a "general combiner," which allows for obtaining hybrid progeny with predictable traits.

Studies of the line focus on its genetic contribution to the development of hybrids, in particular, on the analysis of the inheritance of 1000 kernel weight. RHA C B is also used in breeding for modifying the oleic and linoleic acid content in sunflower oil.
