10 August 2026
The hybrid is characterized by tall growth and large leaves. The drooping head helps reduce the risk of bird damage and protects seeds from sunburn. The plant possesses a high capacity for seed filling in the central part of the head.
Oil content in the seeds varies from 46 to 52%. The hybrid is adapted to hot climatic conditions; however, in case of water stress at high planting density, irrigation is recommended. The recommended plant density assumes a distance of 25–30 cm between plants in a row with row spacing of 70 cm.
