10 August 2026
The hybrid is mid-early, with a ripening period of about 120 days. Plant height varies from 170–175 cm without irrigation to 180 cm under irrigation. The head is characterized by a strong downward curve, which ensures a high degree of seed retention after maturation.
The seeds of the variety belong to the large-fruited category: their length is about 25 mm, width is 10 mm, and color is black with stripes. Potential yield exceeds 3 t/ha depending on growing conditions.
The plant is a traditional hybrid not intended for IMI or SU technologies, so standard herbicides and inter-row cultivation are used for weed control. Seeds are subject to mandatory fungicidal treatment; additional protection against downy mildew is recommended.
