Variety description

10 August 2026

The variety is a three-way early-maturing hybrid suitable for cultivation in regions with a risk of precipitation during the harvest period. Plant height is 130–140 cm. Harvesting takes place from the end of July to August.

The plant features a semi-pendulous head position, which, combined with rapid seed moisture loss, reduces the risk of white and gray rot, as moisture does not accumulate on the back of the head. The variety is intended for use as an oilseed crop.

As of 2024, it is noted that the hybrid was lost after 2014 due to the loss of parental lines, and work is currently underway to restore it.
