10 August 2026
The hybrid is a high-protein crop, the seeds of which have a white color and possess significant structural density. The thick seed hull acts as a physical barrier during germination, which must be considered when determining seeding density.
The biochemical composition of the hybrid differs significantly from oilseed varieties due to a different breeding focus oriented toward the needs of poultry farming. Physiologically, the plant is characterized by high sensitivity to moisture deficiency and lower drought tolerance compared to typical oilseed hybrids.
