The hybrid belongs to the FAO 550 maturity group. When grown for grain, the yield is 12–13 t/ha with a potential of up to 14–15 t/ha, and for silage — from 35 to 70 t/ha. Morphologically, it is characterized by good ear development, two-earedness is frequent, and grain moisture loss occurs slowly.
The plant possesses increased resistance to fungal diseases, including Fusarium and Aspergillus species. The hybrid demonstrates intensive initial development and high adaptability, maintaining stable productivity in both arid and cool, humid conditions.
The recommended sowing density when grown for grain is 60–65 thousand plants per hectare, and for silage use — 70–75 thousand plants per hectare. The hybrid is intended for use under intensive farming conditions.
