The hybrid belongs to the mid-late maturity group (FAO 500–610). The plants are tall. The grain is of the dent type; the thousand kernel weight is 345–360 g. The ear is regular in shape and contains 16–18 rows of grains, with 38–40 grains per row.
The hybrid possesses high resistance to lodging, Helminthosporium, and stalk and ear Fusarium. It demonstrates good grain moisture release rates, early growth vigor, and medium to good drought tolerance. A pronounced "stay green" effect ensures the leaves remain green until maturity.
When used for silage, it is distinguished by high starch content and digestibility indicators. It shows high production potential on medium- and high-fertility soils.
