Re: HYB:Anthocyanin-Controled crosses.

Chuck, (or anyone else for that matter)
These are the "blues" I already grow; do you know the anthocyanin/ AVI dosages
for any of them?
Dusky Challenger
Indigo Princess
Swazi Princess
Country Sky
Dresden Dancer
Sky Road
Space Viking
Six Pack
Unfurled Flag
Is it safe to assume that any TB white is a blue with 4 dosages of I?  Is
there some formula/ or home chemestry project for spotting the ones that are
not? I should look in the archives I know some experiments have been
mentioned... but it seems the mention has always lacked the how-to.  Other
than that it seems like I have a workable grasp on the blue part of the
Is yellow pigment (carotenin, right?) expressed differently at different
dosages? Is it dominant?  I have it in my head that there's some kind of
parent child relationship between the color breaks for yellow and pink in
irises... can't remember which way it went. 
gosh, we almost need to get John to mke a new code just for color genetics
posts.....whoops... how long has this one had no code?

As far as I can tell  AVI is independent from the cell sap disolved
anthocyanin. I saw AVIs in standards of Ziggy, which are an amber
yello-, without disolved anthocyanin.

Two dosages of "I" will apparently  turn a black with one dosage of
AVI and one dosage of anthocyanin, into a yellow. This hasn't been
confirmed with a controlled  cross, but seems to be so based on

Your theories re geen may pan out. But this is only one type of green
There are several different greens.

Let me see if I'm crossing O's.  You are saying that black is usually a

of the AVI in the presence of yellow pigments, I think I understand that
part.  And you are saying that the AVI genetically speaking comes from
aphylla, but since there is no yellow in aphylla we don't see

Assuming everybody got off on the same track with me, are you saying
these AVI pigments are the type of anthocyanin pigments that express
through a full dosage of the I (inhibitor) gene.

If that is true, and the AVI can be expressed with yellow-to give black-
then... I think what I need to know is do the AVI inheirit
independently from
the type of anthocyanin that is expressed in say Breakers or Dusky

I remember that one of the ideas that got me interested in greens in
the first
place was that yellow and blue pigments are expressed in different
layers in
the flesh of the petal.  So in the brain fog I'm thinking... if you
could get
a self expression of yellow in one layer, and a half I inhibitor self
expression of blue in another layer... then maybe you could get green.
But if
the AVI's are seperate from the layer of anthocyanin...then maybe you
just get a yellow base and top off with AVI.   Am I mechanically in the
ball field?
