Variety description

10 August 2026

The variety belongs to the medium-late maturity group. Due to the prolonged development period, the flowering phase of this variety often coincides with periods of high temperatures and low air humidity.

The plant is susceptible to heat stress, which can lead to a decrease in the harvest index under adverse weather conditions, and also significantly affect the fatty acid composition in the seeds, in particular the palmitic acid content.
