Stephanie Knight, Account Manager for Rijk Zwaan Australia presents two cos lettuce varieties for Australian growers. Gradara RZ and Tuccadona RZ Knox™ were featured at the East Gippsland Vegetable Innovation days (EGVID) trials during May 2020 at Lindenow, Victoria, Australia.
In recent years we have been seeing a change in cos lettuce towards more midi sized, compact cos varieties, especially for sleeving and processing.
Gradara RZ is a fantastic product for processing, strong against tip burns and in the internals, It is very slow bolting and features good weight. A nice clean base also makes it ideal for sleeving in the fresh market with a very long harvest period.
Tuccadona RZ Knox™ is our first variety with the Knox™ trait that is working well from Spring through to Autumn. With the Knox™ trait this will be very interesting for processors as it can extend the shelf-life. It also has good vigour and leaf colour is a bit darker. Commercial seeds are currently available.
The award winning Knox™ trait provides additional shelf-life and improves the consumer experience by delivering fresher lettuce and helping to reduce waste. Knox™ is a game changer in lettuce breeding! Developed after more than a decade of R&D, the natural trait delays the ‘pinking’ or browning of cut surfaces in lettuce by days. The whole supply chain benefits from fresher lettuce, thanks to Knox™.
