Varieties with documented resistance
No variety here is described as resistant in words. The varieties below are rated on a numeric scale instead, which records how each one performed, susceptible ones included.
Varieties rated for this disease (63)
Rated on a 1-9 scale where 1 is most resistant, listed from the resistant end. A rating is a measurement, not a verdict: the susceptible end is shown too, because knowing what to avoid is half of choosing.

Rated by its breeder: the publisher of the rating also bred that variety. Still a measurement on the same scale as its rivals, but not an independent one.
