  1. *20–50.9% average %Red. Potential = moderately affected (MA); 51–100% = highly affected (HA)
  2. **HA or MA +HS = highly susceptible (HA); MA+MS = moderately susceptible (MS); HA+LS = intolerant. Percent yield reduction potential was calculated by dividing the percentage reduction of plant growth or yield of a given cultivar on the percent reduction of the highest one (cultivar) multiplied by 100.
