Yes.
That's what he's been doing, but his complaint is that the majority of his red-bearded white seedlings have beards that are less red than the parents - more orange.
I was wondering if there is anything he can learn about the parents that might skew things more towards deep red and less orange.

So goal is white flower with red beard?  Not pink with red beard.

Then he will need to go for inbreeding. Best of F1 sib crossed or F1
back to parent.

Thanks Chuck. I thought the intense red beard probably has some other
color with the tangerine.

I haven't seen Tom's seedlings, other than the one he's introducing, but
from what he told me, he's been crossing his existing red bearded whites
with either other people's red bearded whites (I think he mentioned
ARCTIC FOX?), getting mostly t-bearded whites, but more orange looking
than either parent.

To make sure I understand what you are saying, he will have better luck
using the reddest bearded yellows (hard enough to find!) with his
red-bearded whites?

 From that kind of cross, won't he get a bunch of t-bearded pinks and
yellows as well as whites?

But they will all have a better chance of having redder beards?

What about the water soluble yellows? uh oh, there went the memory
cells- are those the ones in orange petals? So red bearded orange or .....

3) to get red with lycopene. you also need some yellow. It happens

this

way with tomatoes. A cultivar without beta-carotene is pink. all red
tomatoes have 20-40% of pigment is yellow. Because of how pigment is
produced at molecular genetic level it is easier to get combination of
lycopene and yellow with white with tangerine beard and with yellow

with

tangerine beards.

So for a pink with intense red beard, I would start with reddest

bearded

pinks. The red bearded whites (and red bearded yellow) won't get you
there as different chemical process with white, which disappears with
pink flowers.

A question from a local iris breeder working on red-bearded white
irises. He says he crosses the reddest bearded whites (or whatever)
with the reddest beards he can use, and is frustrated that most of the




seedlings have beards that are less red, more orange than the parents.

I wondered if maybe the true red beards have some blue or other

pigment

mixed in, whether maybe some other color beard crossed with red would
give a higher percentage of true red beards.

Any of you know the trick to getting/keeping the 'true' red beards? Or
know anybody who would know?

Seems like, if it was 'just' fully recessive, crossing two red beards
would give mostly red beards.
