Based on my gardening observations/experience I think you are right on
target Donald - healthy, vigorous plants are much less susceptible to
disease.  And health can be strongly related to the individual
cultivar's ability to "cope" with stress.  

I really don't understand the cultivars that seem to be thriving under
really hot and dry conditions, then rot after a heavy rainfall.  My soil
is gravelly, loam, raised beds, drainage is excessive, but these plants
still succumb to major rot and is 100% cultivar specific.  It seems to
be related to the rapid change in growing conditions (like blossom end
rot in tomatos), but it raises my curiosity as to what is going on
underground/physiologically with these guys.  Sudden change in ?  All
the salts suddenly in solution changes potential across root membranes? 
Maybe the roots suddenly swell up and get cracks in them that let the
evil bacteria have its way.  Any plant physiologists/pathologists out
there want to take a stab at an explanation?

aka The Rot Queen - gonna have to give my title away - very little rot
for me this summer, but all the cultivars rotting for other folks this
year probably died here long ago.
