The International Bremia Evaluation Board for the US (IBEB-US) recently denominated a new race of Bremia, BI:9US.
Many Vitalis and Enza Zaden varieties are already resistant to this new Bremia race. And we are building a pipeline of varieties with a wide range of resistances. In the production section on our website you can find an overview of our lettuce varieties and their resistances.
Bremia lactucae, causing downy mildew in lettuce, is genetically very variable. Breeders are working together to monitor the changes in the Bremia population in response to the introduction of increased resistances. Enza Zaden offers a wide range of solid varieties with excellent field performance, outstanding post-harvest quality and high levels of disease resistance. In combination with your usual preventive treatments, these varieties ensure a high level of protection, leading to a successful lettuce production.
