Subject: [iris-photos] Re:HYB:TB: Mid
America seedlings T 101A and T101B
T101B is intriguing. The purple-blue veins
look like the Ghio/Keppel "Line and Speckle" pattern--except the markings are
"proximal" rather than "distal" on the fall. I'd love to play with
crosses between the ones like this and some of the descendants of
Cinnamon Sun/Ghio 88-180P types, such as PUCCINI or QUANDARY, IMPULSIVE,
or EXPOSE. I have four or five from the family here, including 88-180P
itself and hope to see seedlings bloom from IMPULSIVE in the spring, but
they probably won't show the pattern, as the one cross of which I'm
thinking is an outcross to a solid self.
What makes me so curious is that NOTORIOUS is a
lot more like the Mid-America seedlings we've been looking at, and NOTORIOUS
is one parent of the Ghio 88-180P principally responsible for the "Line
and Speckle" group. I am suspicious of a connection--and wondering if we
are looking at long generations away from ancestral *I. variegata* patterns
with a group of alleles involved that originate with that ancestor. I
have a hunch--quite possibly wrong--that this will prove to be the
case.
Or else there is a group of genetic
components--separately establishing the veins versus solid pattern, and
another determining where the veins (and speckles) are expressed--sort of an
analogous series to the plicata-luminata-glaciata set.
This Line-and-Speckle is definitely <not> a
plicata variant, however. It is something else entirely--Keppel and Ghio
have tested this question out and know it to be separate
from the plicata series.
Just thinkin' and dreaming up more
mischief......
