The hybrid belongs to the mid-late maturity group with an FAO number of 300–360. The plant is tall, forming a Flex-type ear with 16 grain rows. The thousand kernel weight varies from 330 to 350 grams; the grain type is dent.
The plant features a strong stalk, ensuring lodging resistance, and is characterized by tolerance to Helminthosporium leaf blight and Fusarium stalk and ear rot. The pronounced stay-green trait allows for longer maintenance of green leaf color, which positively impacts silage quality and fiber digestibility.
