Re: HYB:Anthocyanin-Controled crosses.
The combination of the anthocyanin dephinidin with the yellow
pigments change appearance of the colour. Dephinidin on a white ground
is blue ( i'm not making distictintions between indigo etc , just
between purple and "blue") while with carenoid yellow is purple . On
a pink ground it is a rosy violet.
You need to read what is the combinations that you are looking st. Thus
some hot water extractions until you can see and understand the
disctinctions for yourself.
AVI is seperatly inherited from the soluble delphinidin. Thus you can
have AVI without watersoluble pigment. AVI with cartenoids give a
mustard like or olive colour depending on intensity of pigments
present (warning this is a best guess based on what I currently
understand, no experimental confirmation). Without cartenoid resent
probably can give the purple you see in white Mutant etc.
AVI plus delphinidin and no cartenoid, also gives purple, but a dark
purple. Plus cartenoid gives black.
Cartenoid is dominant over non cartenoid (usually) . That is cartenoid
(yellow or pink ) crossed to a blue (no cartenoid) produces purple
(regular, not deep purple). This is ignoring recessives. All will be
purple if the pink (or yellow) has anthocyanin is removed by recessive
reduction of anthocayanin (wwww) or half yellow half purple if
removed by "I".
I have found some cultivars with water soluble yellow. Sea Quest has
water soluble yellow in standards. A couple of yellows with very smooth
hafts have water soluble yellow as well as cartenoid yellow. But
generally there ae not many TB cultivars with water soluble yellow.
Think of Dusky challenger as a schreiners blue with AVI added. They
are seperate factors. But are needed together to produe dark purples

that is a really nice run down... clear, concise, and answers the
question I thought I asked.
Just one little fuzzy-ness. You said "blues" are
not AVI but then said Dusky Challenger is likely AVI. I expected DC
(even if it's a guess) AVI, but it sounds like you're saying DC isn't
isn't blue as in isn't from a long line of Schreiner's blues. Am I
something? I remember someone saying roughly, "there is no true blue in
if you really look even the bluest blues are really quite indigo." Is
what you mean?
Now I feel like I should get out RHS color key and discuss what
counts as a "pastel" yellow. Can't as I don't have RHS color
the temptation is there.
Your general guidelines seem to be exactly what I
need to start in the "right" direction to test my theories... but I've
culled a seedling I should have kept.
