Variety description

10 August 2026

The hybrid is mid-maturing and has a dent grain type. The plant is medium-tall, possesses a powerful root system and a strong stalk, which ensures resistance to late root lodging.

The variety is characterized by good early development, high drought tolerance, and rapid grain moisture loss during ripening. It shows resistance to Helminthosporium leaf blight and rots.

The hybrid is multifunctional and intended for use for grain, silage, and corn-cob mix. It is capable of consistently forming yields in hot climate conditions with moisture deficit.
