---It has been a while since I've read "The World of Iris", but I also remember it as you do.  That would be an advantage of going to tetraploid I. tectorum X modern TBs.  But getting the tetraploid tectorum is a problem in itself.
 
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.
---Right.  Does anyone here know what color the F1 of I. varigata x I. pallida is?  Purple, if I remember right.  But I haven'tmade the cross myself, and I am not sure I remember what I read.

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
