The hybrid is simple and belongs to the mid-early maturity group with FAO 280. The plants have a strong stalk, high resistance to lodging, and ears with 14–16 rows of kernels. The yield potential is 13–15 t/ha; under production conditions, figures range from 8 to 12 t/ha at a grain moisture of 12–15%.
The variety is characterized by very high drought tolerance and tolerance to common smut, head smut, Helminthosporium leaf blight, and European corn borer. It is suitable for cultivation in monoculture and late sowing; however, it is not recommended for early sowing in waterlogged soils due to low frost resistance.
The recommended plant density before harvest is 75–80 thousand plants per hectare under sufficient moisture and 65–70 thousand plants per hectare under conditions of insufficient moisture.
