Hi Chuck,
Thank you. That gives me good news and some
hope as I wait for the others to bloom next year, as well as looking
forward to making a sibling cross. I no longer grow Lady Celeste, so that 'cross
back' probably won't happen. :_)
LC was a very vigorous grower and increaser,
that is partly why I chose her as one of the parents. Another reason is she
had at least 9 buds per stalk with decent branching. Sly Fox, in
my opinion, grows well some years, but not all years. But SF
has great substance, decent branching, and a gorgeous
form. Crosses between the 2 plants seem to have promising
potential.

Subject: [iris-photos] Fwd: Breeding for
blue beards on white
A follow up. I was thinking of another cultivar when I posted. I don't
have a photo of Lady Celesta on file. I double checked
registration
Lady Celesta actually would seem to be a good choice on
this search. It
does have a dark beard. You can darken beard by combining
the cartenoid
with anthocyanin. Need to do sib x sib or sib back to Lady
Celesta.
Use whitest sib you can. check beards closely when selecting
seedling
to use .

Using Sly Fox would not be
the best route towards this goal.. Any iris
with a cartenoid beard would
work against increasing anthocyanin.
There have been a
few good iris that aproach this goal. If you can
find it MARGARET VIOLA
WHITE by Lloyd Zurbrig would be a good one
to use. The best in this colour
that I know of.
To get a dark black beard on white, you
need something heavy in
aphylla inheritence to start with and then as many
doses of the
dominant reduction of anthocyanin "I" as you can get. You need
the
anthocyanin enhancement gene "Ae" to get the dark beard, and this is
in
a lot of dark blues/near blacks that have aphylla in background.
Then
as many dosages of I as you can get. This route has produced a
number
of pale blues with very dark beard such as Codicil, and
Blackbeard.
Then cross to white with anthocyanin in beard. As beard gets
darker it
is harder to repress th
e anthocyanin in petals, so it ends up
being a
compomise. Using something like Sly fox could darken beard by
having
both cartenoid and anthocyanin in beard. It would take some
doing,
(many generations) but need to cross to something near black with
dark
beard, not a light blue like Lady Celesta. Lady Celesta doesn't
have
the Ae gene.

Thank you Chuck, yes that all does make
sense.
Question: the goal with this
specific cross was to see if I could come
up with a pure white TB with a
dark blue beard, how probable is that?
