Variety description

10 August 2026

The variety is a mid-early three-way hybrid with an S 230 maturity group. Its distinctive feature is the "stay-green" genotype, which ensures long-term retention of green leaf color at the end of the vegetation period.

The plant is intended for agricultural use, specifically for grain production or as a catch crop. Research on susceptibility to maize smut and European corn borer did not reveal significant deviations of the hybrid from other varieties of the company's breeding.
