The H251B line is used primarily as a parental form or an object for molecular genetic research. The main distinctive characteristic of this line is its fatty acid profile, namely a reduced content of palmitic acid in the oil.
This line is specialized breeding material and not a widely distributed commercial hybrid. Detailed data on its morphological traits, such as plant height, as well as information on resistance to diseases, lodging, or maturity group are absent in open publications.
