Re: Re: Tectorum X bearded update

Hello Walter,
Good to hear from you again. Actually, we're thinking
alike, because I'd already thought about your point
about the two whites (of different species) combining
to still make purple. That would be a classic example
of complementation, but I sure am hoping that instead,
the white gene in tectorum is analogous to the
glaciata white gene of Kupari. 

As for your suggestion to use dominant whites
(non-purples), I like that idea, but I'm very confused
about the occurrence of this type of gene in the
diploid beardeds. From "The World of Iris", I had
gotten the impression that the dominant white (reduced
anthocyanin) gene had come from some middle-Eastern
tetraploids. It's implied (but maybe I've
misunderstood) that it wasn't already there, in the
European diploid gene pool. But more recently when
I've discussed the glaciata gene (recessive absence of
anthocyanin) on the iris-forums, I'm getting the
impression that it's fairly uncommon in the diploids.
'Kupari' seems to be one of the only known glaciata
dipliods. So, which gene is responsible for
lack/reduction of anthocyanin in the typical old
yellow diploids??? If it's the dominant one, these
would be good beardeds to try with tectorum.

Also, as you mention, there is apparently a dominant
amoena gene in the diploid bearded gene pool. I've
gotten some amoena F1 from 'Kupari' X suaveolens var.
rubromarginata and have tried using those with
tectorum but haven't gotten any viable seeds yet.

Good luck with your lycopene pink arilbred project. I
hope you also find some spare time to tinker around
with tectorum X beardeds. 
Take care, Tom
