amphibian - I doubt that it does in part because there is probably a lack of adequate data at this stage. The only variety that I have heard of is Lady Balfour which has a high resistance rating in the database but is not living up to this billing when A2-Blue13 is present.
As a cynic I do not believe in total resistance and so I simply use the numbers to see how one variety stacks up against another, eg Romano (son of Desiree) has greater resistance to blight on foliage than Desiree itself .. and I will continue to use this approach until such time as somebody announces that (say) Romano is susceptible to A2-Blue13 .. not a lot else one can do.
