Variety description

10 August 2026

The Walton variety is mentioned in studies dedicated to breeding and leek resistance to diseases. Specifically, the variety demonstrates a response to infection by rust (Puccinia allii).

Upon exposure to the pathogen, damage in this variety is most often manifested on older leaves and their tips. After removing the affected areas, the main part of the plant retains its marketability and remains suitable for use.
