David Holm, potato geneticist, wrote (~ ad lib from memory): potato
growers check their vegetative potato 'seeds' every year to make sure
they haven't visibly mutated and "drifted" away from what they were bred
to be.

David - any idea of what proportion of rejects show up?  Would that be
likely to be comparable to the proportion of mutations that might affect
less visible characteristics, such as the ones we were talking about in
irises (water relations, temperature adaptability (frost), temperature
thresholds for bud break, ..)?

Thanks for all the interesting information.  And apologies if I got the
name or the content wrong.  Way behind on email & can't find the post.
