| Yes, the overall disease ratings of all varieties can change year to year based on the pathogens, crop density and the environment. However, most individual varieties are usually quite consistent with regards susceptibility/resistant to a specific disease (when present), at least over 3-5 years.
We usually find independent ratings from universities are the ones to use, because seed companies are sometimes very optimistic with their disease ratings (in an attempt to promote their varieties).
