Are you saying that it's impossible to select for TBs that show a resistance
to rot?

I'm curious about this since it is one of the things I've been selecting
for. The other major fault is susceptibility to leaf spot.

> Let me point out that I don't believe any hybridizer has ever selected for
rot resistance. To do so you would have to deliberately infect your plants
and see how they respond. Everyone that has grown TBs for many years has had
a season or more in which the plants might be devastated by soft rot.  Even
under that type of condition the survivors tell you very little about their
resistance. You would have to rule out microclimates and many other factors.
In my opinion Iris people have not assembled any information that can say
anything at all about rot resistance. Good scientific investigations have
not been done that give us this information.
