The hybrid belongs to the mid-season maturity group (FAO 330) and produces dent-type grain. The plants have a medium height and high ear placement, demonstrating good tolerance to lodging, Helminthosporium leaf blight, and moderate resistance to smut diseases.
Distinctive features of the hybrid are the ability to retain green leaf color for a long time, a thin cob cob, which ensures a high grain yield, and intensive moisture loss during maturation. The Optimum® AQUAmax® technology provides high efficiency of moisture use under drought conditions.
The hybrid is suitable for monoculture and minimum tillage. The recommended plant density at harvest is 65–70 thousand plants/ha with sufficient moisture and 60–65 thousand plants/ha with insufficient moisture. The variety is suitable for late harvesting, while early and late sowing dates are not recommended.
