The variety has the status of an improved cultural accession recorded in international genetic resource databases. In modern breeding, it is valued as a valuable genetic material for the transmission of resistance traits rather than as a variety for industrial cultivation.
The plant possesses complex resistance to a number of pathogens, including basal stalk rot, head rot, and Phomopsis (stem canker). The variety is regularly used as a control sample when conducting scientific research on mechanisms of sunflower resistance to diseases.
In scientific literature, the variety is also mentioned in the context of physiological experiments and genetic analyses. Detailed morphological characteristics, yield indicators, and oil content are absent in open publications.
