Now if we had some way to compare those that do well for you and those that 
do well for Donald and other iris people we might really have something 
valuable. Especially if it were done in a way where we did not have to depend 
on antidotal information extracted from a pile of notes, emails or lists of 
pretty flowers. We might even form a coalition of Northern, Southern, Eastern 
and Western people interested in irises that perform well under 
adverse/diverse growing conditions and produce a list of such irises. I have 
no idea how this might be done. Maybe a symposium or something. <g>

I believe you are entirely correct from a genetic prospective. While rot 
itself may not be genetic, there is a wealth of antidotal information from 
this list and other sources supporting the hypothesis that susceptibility to 
rot is. We see this often in post concerning certain cultivars and lines of 
cultivars being rot prone. It is not uncommon to read post where one comments 
that they have seedlings from a notoriously rot prone parent that do not rot. 
That is what would be expected if the susceptibility is a recessive trait. 
Sadly it may not again manifest itself again for several generation into the 
future but it ultimately will. And, that gene will always be there. But, some 
very floriferous blooms will probably be developed in the interim.

I do not believe my actions are far out of line with others having 
hybridizing interests. I sometimes see a trait in a bloom I want to 
intensify/reduce/change. I find myself, against all reasonable standards or 
intelligence, using a pollen based on that bloom characteristic. There is no 
question the change takes place easier and quicker that way. When we do this 
it complicates what we truly seek. That bloom characteristic in a great 
plant!

I would certainy appreciate seeing a list of the "adversity" champions you 
have identified.
