Variety description

10 August 2026

The hybrid belongs to the early maturity group. The plant is characterized by very good early vegetative development, resistance to stress conditions, and adaptability to poor soils. The variety possesses high resistance to lodging, as well as to ear and stalk Fusarium, common smut, and European corn borer.

The grain is distinguished by a rapid moisture loss process before harvest and a high grain yield from the cob mass. The variety has a universal purpose: cultivation for grain, silage, corn-cob mix (CCM), as well as for the production of grits and bioethanol.

The recommended seeding rate is 80,000–85,000 plants per hectare when grown for grain or CCM, and 95,000–100,000 plants per hectare when grown for silage. The short vegetation period allows for flexible planning of sowing and harvesting dates.
