Improved lettuce with KNOX
By Dave Harrison
November 2015 — Rijk Zwaan has introduced a trait in its lettuce varieties that ensures that the leaves discolour less rapidly after cutting…
The vegetable breeding company has nicknamed the trait “KNOX” and it extends shelf life by about two days. The benefits will also lead to a better consumer experience as consumers can enjoy a bag of pre-packaged salad much longer.
Rijk Zwaan worked on the development of KNOX for a total of 10 years. About 10 varieties in different lettuce types now have this property. The expectation is that the range of KNOX-based varieties will quickly be expanded in the next few years.
