The Ha-26-OL line is a specialized genetic material, not a standalone variety for commercial sowing. The total oil content in seeds varies from 31 to 36 percent depending on growing conditions.
In breeding programs, the line is valued for high oil quality. Scientific literature also mentions modifications, such as the maternal line Ha-26-OL-SOL, which possesses resistance to downy mildew due to the presence of the Pl6 gene.
