Variety description
10 August 2026
The variety is early-maturing, with a period from transplanting to harvest of about 50–60 days. The plant forms large, round, and dense heads with a well-closed base. Wrapper leaves are blistered, firm, and have slightly wavy margins.
The leaves have a succulent and crunchy texture. The variety is characterized by high resistance (HR) to powdery mildew and intermediate resistance (IR) to Lettuce mosaic virus and Fusarium wilt. It shows good tolerance to tipburn and resistance to mechanical damage during transport.
The variety is intended for cultivation in open fields in spring and autumn cycles. It is characterized by cold tolerance and adaptation to temperature fluctuations, but it is sensitive to drought and requires regular irrigation to ensure a high-quality yield.
