  1. *Proportion based on: total number of varieties for which varietal information is available (i.e. discounts varieties not in the Recommended Lists and variety mixtures). RLS proportions are based on the varieties in each dataset from 2012 onwards, when resistance ratings were first published. In this paper, ‘highly resistant’ is defined as a rating of 7 or above, on the standard 1–9 disease resistance scale
  2. **Any Resistance is defined as the variety having a rating of 7 or above for one or more of the three diseases of interest
