The hybrid is mid-early with a maturity period of 85–90 days. The plant is tall, reaching 270 cm, and the ear is formed at a height of 95–110 cm. The grain is of the dent type, with 14–16 rows of grains per ear.
The plant possesses high resistance to root lodging and tolerance to loose smut, common smut, helminthosporium leaf blight, and fusarium. Thanks to Optimum® AQUAmax® technology, the hybrid uses moisture efficiently and is stable under drought conditions.
Intended primarily for grain production, as well as for the manufacture of starch and alcohol. Characterized by rapid moisture release during ripening. Suitable for cultivation in monoculture, but not recommended for minimum tillage technologies.
