Variety description

10 August 2026

The variety is a tall-growing plant that, during its period of widespread cultivation, was noted for its high productivity and adaptability. Due to its genetic significance, it was actively used in breeding programs to develop new varieties in Europe and the USSR.

The plant possesses genetic resistance to stem rust (Puccinia graminis) conferred by the presence of the Sr23 gene, which induces a necrotic reaction in the pathogen. The variety has also been used repeatedly in biochemical scientific studies as a model object for metabolic research.

Currently, the variety belongs to the heritage category and is preserved in international gene banks as a valuable resource for breeding work.
