Variety description

10 August 2026

The hybrid is classified as an early-maturing maize variety. In agronomic studies, this variety is often contrasted with stay-green type hybrids, which possess a 'green stem' effect.

The primary purpose of the crop is feed production. At specialized institutes, studies were conducted on the morphological traits of the plant, such as stem height, ear placement height, and leaf surface area, as well as the variety's response to sowing density and fertilizer application.
