Variety description

10 August 2026

The line is not a variety in the consumer sense and serves as source material or a component of hybrids, particularly in the role of a paternal form. The object is widely used in scientific work for conducting molecular genetic analysis, for example, by the iPBS method.

Information on morphological traits, such as plant height, lodging resistance, maturity group, or commercial yield indicators, is absent in open publications, as this material is not intended for widespread commercial cultivation.
