Tom--and others interested,
Chuck Chapman mentions in one of the recent posts
that the type of recessive white of the Kupari clone in circulation (I assume
you have the same one) is a glaciata. That was one of the three possible
recessive whites encountered in tall beardeds, and your obtaining plicatas, both
from this group and from the cross with *Iris variegata* tends to confirm
that. The recessive whites that show up in pallida populations should, I
would think, include not only this type, but the w-sub-1 and w-sub-2 as
well. Since I can't reproduce subscript easily in this format that "-sub-*
form is intended to indicate the character in subscript.
Each of these recessives represent redirection
of the anthocyanin production of the particular variety or varieties that carry
them at different points in the chain of chemical events. The 'Ostrey
White' clone of *Iris aphylla* is also a glaciata type white from what I have
read, so crosses of the white Kupari clone with it would be interesting.
Forming triploids from 4n x 2n parentages is one of
the pathways to tetraploids. Crosses from the triploid to diploid pollen
sources could presumably on occasion give rise to tetraploid offspring
from unreduced gametes in the triploid. I'm hoping this holds true with
siberians as well (it should), but in any event, a great many attemps and a fair
amount of luck are required to get seed, seed with embryos, germinated
seedlings, and seedlings that survive to bloom and increase.
I would like to use some tetraploid siberian pollen
on Christy Hensler's JS-series JI-type seedlings to see if any triploids can be
produced. Similarly, tetraploid siberian pollen on some of the sterile
*Iris pseudacorus* hybrids with *ensata* clones, especially some of the more
full-bodied ones, is something I have in the back reaches of my filed-away
intensions.
Too many projects, and too many things I want to
try have always been part of my iris experience, and one of the things that has
tended to bog down my productivity. My intentions of getting some
seedlings from Peyrard's *timofejewii* x *variegata* hybrid have not yet
bourne fruit, especially with tetraploid TB's and some diploid BB's such as
'Pink Ruffles.'
Since I don't have room to plant the seedlings I
*do* have and grow I need to be very focused and conservative about
projects. But what fun is that?
Your *missiouriensis* X siberian hybrids intrigue
me. I assume these were diploid 28-chromosome siberians. Is that
true? Or were they Sino-siberians of the 40-chromosome group? I will
echo Christy Hensler's comments and say I also find them lovely and have
the same curiosity about them.
