My thought on this was to produce seedlings that contain both the form and
rebloom genes, a wide variety, then produce 1,000 seedlings.  Reselect groups,
amoenas, Emma Cook, fall bands etc..  Choose the best in each group.  Produce
another 1,000 in each group.  Eventually select the rebloomers in each group
and recross them.


If only I'd come up with this 30 years ago!  ;-)  Another child filled day.

Betty W asked on Facebook
<about iris plants--I've noticed that the strongest plants seem to have
the ugliest blooms. (less modern of form) Is this true? Is there limited
plant ability? If it gives good plants habits, it doesn't have the
ability to give good blooms? Linda Mann, is this what you are thinking
about rebloomers?>

No, I think it's possible, just very very low probabilities for me at
this point in my breeding program.  The more inbred all the traits are,
the higher the probability to get them all combined.  This is what Chuck
was talking about when he was asking me all the questions about getting
plant health/vigor in seedlings involving parents from "incompatible"
climates.

So what I'm thinking is that if I had a population of seedlings that
when interbred would always (say, more than 80% of seedlings) produce
rebloomers that had the rebloom traits I wanted, plus a population that
when interbred <always> gave the form, colors and vigor I wanted, then
crossing and back crossing would give quite a few rebloomers with the
form and vigor (leave recessive colors & patterns out for now).

I have or am very close to having the population of seedlings that will
usually give good form when interbred, but have no population of
rebloomers that when crossed with each other will reliably give rebloom.
  & other people's rebloomers don't reliably rebloom for me either,
so.... :-(  & since hot weather rebloom seems to be recessive, it may
take awhile to get seedlings that have that trait and are able to
express it under my growing conditions.  For all I know, I have a
crateload of seedlings that can rebloom in hot weather, but just can't
do it here.  Not likely, but unknown.
