The line is a specialized breeding object and is not intended for mass commercial production. It acts as a parent component in commercial seed production programs; in particular, it is mentioned as one of the parents in the pedigree of the PHHHN line.
The plant is homozygous and stable. Since the line is not a hybrid for commercial fields, detailed agronomic characteristics such as plant height, maturity group, or field resistance to diseases are not published in open sources.
