Re: HYB: Clarence pedigree
Fred, I find that particularly interesting that the seedlings were all
glaciatas or luminatas.
One of those who were in on the discussion some time back (the one that
involved Chuck Chapman) would have agreed with you, as he also thought
CLARENCE was amoena-luminata. Chuck was sure that his own interpretation was
the correct one.
The fact that these results you cite from that parentage does tend to indicate
some close connection between that type of zonal with the plicata alleles.
From your comment, "that type of zonal" it sounds as though you view the
zonals as a group of not-necessarily-the-same pattern. The pattern in UTAH
VALLEY for instance was fall-only, and had those behind it that had light
colored hafts on the falls, especially around the beard.
GLORIOLE threw a lot of those, and the GREAT LAKES-CHIVALRY heritage had light
areas around the beard and across the haft, but most pronounced around the
beard. CONQUISTADOR is a grandparent of Great Lakes--and of SAN FRANCISCO,
LOS ANGELES and the seedling that is the pollen parent of ADVANCE GUARD, which
may have been San Francisco itself, certainly is suggestive of a common
element being possible. There is a possibility that one of the pl forms may
have been present in these, although JUNIATA, the presumably diploid mother of
Conquistador, is a "B1M" medium blue self.
VICTORIA FALLS has a light zone around the beard, but this is heavily lined
with the fall color in the veins, tending to obscure the "zonal" impression.
The idea that zonals and BC's both may depend on some of the pl alleles for
their existence is a fascinating idea, as neither the broken colors nor the
zonals show any plicata lining or stippling in their color patterns. BC's--at
least BATIK--have been known to show wedge chimeras of out and out plicata
patterns, indicating a single gene difference separates the broken color
pattern from phenotypically normal plicatas.
Irises are astonishingly more complex than what was once thought.
