Re: RE: genetics behind glaciata, plicata etc.

Hi Tom,

Thanks,

I've looked at your 'Kupari' x variegata hybrid photos before, but was
never thinking in terms of genetics of patterns.  I just looked out of my
interest in how the cross turned out (and because I really like diploid
hybrids in general).  I'll go back and have another look.  I've always
assumed that the plicata pattern is derived wholly from I. pallida, but
have wondered if there is a kinship to the I. variegata type pattern, which
also seems to be expressed in dark colored veins (which, unlike in I.
pallida tend to fuse on the falls, and be absent or nearly so on the
standards).  Somebody else probably has this all figured out, but I wonder
if both are expressions of the same or related plicata genes?  Does the
plicata gene come from I. variegata in this case to be expressed in a more
"pallida-esk" way.  It is clear looking at the photos that the anthocyanin
is being expressed partly in an I. pallida way in all of them.  It's also
interesting how they all resemble muted versions of existing cultivars that
are supposedly also I. pallida x I. variegata, or at least of this
ancestry.

On the flip side, - I still haven't caught up yet on how glaciata relates
to plicata expression, and the answer is probably already posted on this
forum (still need to go back and read Chuck's recent posts in detail) - but
I wonder, does the glaciata 'Kupari' carry the gene(s) for plicata?

Wonder which species the gene for luminata comes from?  I don't think I've
seen any pattern in any diploid that resembles a luminata - so far.

Saving my main question for last.  Tom, do you have a photo(s) of 'Kupari'
you could post?  I've finally got plants of the thing growing (I ordered
them four years in a row, and till this year they always had/got rot).
This year I potted them up and treated them heavily with chemicals, and
they are going strong.  Not a common problem for me with I. pallida.
Anyway, I've never seen it in flower, nor a good photo of it.  I don't even
know how large the flower is (smallish like the variegated clones or larger
like 'Dalmatica' and a lot of the "pinks"?).  I have another smallish white
I. pallida that may well be a glaciata (yellowish-green haft-striping, and
no hint of anthocyanin that I can see), but I don't believe it is the same
as 'Kupari'.  Won't know for certain until I can compare them directly
though.  One thing is for certain, my white never produces rhizomes so
robust and large as the ones I've received as 'Kupari'.  A couple of people
have prompted me to name and register it, but I still hesitate until I can
compare it with more named white pallidas (not very many of those out there
apparently?).  Guess I should ask here; anyone else have white I. pallidas,
and if so, what are there cultivar names?

Thanks,

Dave
