The hybrid belongs to the mid-late maturity group with an FAO of approximately 270 and has an intermediate grain type. Plants reach a great height, with the ear attached at a medium-low level. Each ear forms 16–18 rows with 28–32 grains each; the thousand kernel weight varies from 330 to 350 g.
The variety possesses high resistance to lodging, Helminthosporium leaf blight, and Fusarium stalk and ear rot. Plants are distinguished by intensive development at early stages, which allows for sowing in cold spring conditions, and also demonstrate moderate drought tolerance and a stay-green effect.
The hybrid's production is characterized by high starch content, good digestibility of the vegetative mass, and high biogas yield. When harvesting for silage, the recommended plant density is 82,000–92,000 plants per hectare.
