Variety description

10 August 2026

The plant is medium-sized, reaching a height of 12–18 cm. The leaves are characterized by a thick structure and a glossy surface, exhibiting high uniformity. The hybrid is distinguished by its plasticity and fast growth rate, tolerates low temperatures well, but is sensitive to drought and extreme heat.

The variety has high resistance to downy mildew (races 1–9, 11–16, 18–20) and intermediate resistance to races 10 and 17. It is universal in use: suitable for the fresh market, freezing, and 'baby leaf' production in open field and protected cultivation during the spring-autumn period.
