Variety description

10 August 2026

The variety is an early-maturing summer bunching onion intended for bunching production. The plant has an upright leaf habit, which facilitates improved ventilation and disease control, and is also characterized by low root implantation.

Distinctive features of the variety are a pronounced color contrast between the green foliage and the white stalk, as well as ease of cleaning. The variety demonstrates high resistance to bolting and a long field holding period.
