The hybrid belongs to the mid-ripening group with an FAO 330 rating. Plants reach a height of approximately 250 cm, with the ear attached at a level of 95 cm. The ear contains 16–18 rows of grain, each containing 35–40 dent-type kernels.
The plant is characterized by a strong stalk, ensuring lodging resistance, and high drought tolerance. The hybrid possesses genetic immunity to Fusarium, Helminthosporium, and common smut, and is also characterized by the ability for rapid grain moisture loss during ripening.
This hybrid is universal and intended for grain production, silage production, as well as processing for biogas and bioethanol. The potential yield is up to 18 t/ha, with an average indicator under production conditions of 12.5 t/ha.
