The hybrid is characterized by tall plants and intermediate ear placement of a flexible type. The grain is dent, with 16–18 rows per ear and 38–40 grains per row; the thousand kernel weight is 355–365 g.
The plant possesses high resistance to lodging, drought, as well as Helminthosporium leaf blight, white rot, and Fusarium. It is distinguished by good early growth and a "stay green" effect, which allows for flexible harvest planning.
The produce has high energy value, good digestibility, and increased starch content. The hybrid is adapted to high planting density; the recommended stand density is from 62,000 to 75,000 plants per hectare depending on the intended use.
