The hybrid belongs to the mid-early maturity group and is a medium-height plant, reaching 165–180 cm. The head has an average diameter of 17–18 cm; the thousand kernel weight varies from 39.9 to 65 g.
The plant possesses high initial growth vigor, cold tolerance, and the ability to withstand stress conditions and moisture deficit. The hybrid is genetically resistant to Orobanche races A–F and new races of downy mildew.
Disease tolerance is expressed by high resistance to Phomopsis, Phoma, root and head white rot, as well as charcoal rot. The variety is intended for cultivation using conventional technology under intensive conditions.
