Variety description

10 August 2026

The hybrid belongs to the FAO 290 maturity group. The plant is characterized by good early-stage development, tall growth, optimal ear placement, and erect leaf orientation. The purpose of the hybrid is for grain, silage, and biogas production.

The variety is distinguished by high resistance to lodging and tolerance to major diseases, including smuts. The grain has high test weight and increased protein and starch content. The Stay-green effect allows the leaves to remain green until full maturity, ensuring flexibility in harvest timing.

The hybrid is suitable for early sowing. The recommended plant density at the time of harvest is 75–80 thousand plants/ha under sufficient moisture conditions and 65–70 thousand plants/ha under insufficient moisture conditions. Not recommended for late harvesting and minimum tillage.
