Constance

Consistent Yields and Premium Quality

Cultivating Lollo Rossa lettuce often brings challenges regarding physiological disorders and pest pressure. Using the 'Constance' variety by Rijk Zwaan allows us to streamline production while ensuring high-quality output. This hybrid has proven its reliability in both open fields and greenhouses, requiring less intervention and providing predictable results for the harvest.

Agronomic Resilience

The standout feature of 'Constance' is its robust field resistance. We have observed excellent tolerance to downy mildew (Bl:16-37EU) and lettuce aphid, which significantly lowers the need for intensive chemical applications. Furthermore, the hybrid is highly resistant to internal tipburn and powdery mildew. For an agronomist, this translates to minimal waste during harvesting and a consistent, high-market-value product.
