Bill Burleson stepped in and was very helpful in
the "Umbrata" question. I sorta fell off the edge the last several
days--for a variety of reasons--and have been out of touch. I still have
good intentions of posting some photos which may even add further to the
confusion.
Bill said something in the (longer) post which
helped me realize something. Linda's originial use of "Umbrata" was to
describe something visual. I picked up and used the term for something
genetic, rather that just visual. There is a continuity between those with
darker fall anthocyanin overlays *without* bordering bands and those
with. There are even some where the pattern is reduced to a band across
the area of the fall.
At least as it grows here, 'Romantic Evening'
either has no band or only the barest suggestion of one on some blossoms, which
I usually attributed to weather. In the cross of ('Swingtown' X 'Romantic
Evening') the following are some of the resulting seedlings. The first is
the one now registered as 'Power Woman.' It shows a minimal band with some
variation from bloom to bloom, fall to tall:
![]() P 1-11 is a bitone, no band, definite fall overlay,
no band, but showing a breaking up of the solid pattern into the lines of the
Umbrata color in the veins, color of the standards showing through
between.
![]() P 1-12 is a self with a black band across the
hafts. This is the (genetic) Umbrata from 'Romantic Evening' expressed
only as a broad thumbpring (?) across the haft area. An alternate
interpretation--the fall band is so wide it covers most of the fall, leaving
only a very restricted area showing the dark overlay. (This seedling has
been discarded)
![]() In a cross of 'Great Gatsby' X 'Romantic Evening'
the following appears as one of two amoenas out of eleven seedlings;
others were bitones, one was a dark self. This seedling is numbered P
2-4. The beard is dark yellow, not red-orange. This seedling
illustrates the effect of what I have written as "I-sub-s" but if I had access
to a font that would carry accross our various media, this would be a capital
eye with a subscript "s" referring to the weak dominant inhibitor from
'Progenitor.' I add this because I sense confusion with my writing this
out as "I-sub-s." I could just as easily have said "Cook amoena factor" or
"Dominant amoena factor" or any of other conventional expressions. TWOI, I
think, uses eye with the subscript "s".
This flower shows the effect of two doses
(presumably) of the factor, *plus* the overlay from RE, a faint border of medium
violet showing on the petal on the right near its outer edge. That border
color is much darker than that of the standards, as in 'Mastery.' This
seedling is being used very cautiously in breeding as it has neither branching
nor budcount.
![]() The seedling above crossed on to 'Wild Wings' (a
very dark RE bicolor) produced the following variations (only a sample of the
cross):
R 12-A (temporary designation. This is
growing in Tennessee and I don't know it's actual number)
Strong bicolor, either no "I-sub-s" or one dose
only, curious absence of pigment in edge of standards irregularly expressed,
strong Umbrata, red beard. The difference between the underside and top
side of the fall is very apparent with the flared up fall edge.
![]() R 12-B (temp. designation) Near amoena
(presumably two doses of "I-sub-s," Umbrata expressed over violet ground
color, narrow fall band consistenly expressed, orange yellow beard. The
fall dark color "shadows" the fall underside as well.
![]() R 12-C (temp. desig.) Strong Umbrata,
no band, on what may be a self of blue. Note the darker edge of the
standards. I do not believe that would appear on an "I-sub-s" bicolor, but
who knows?
![]() Now, here is one for fun: R 60-1: 'Lotus
Land' X P 1-9: sib to 'Power Woman'--I take this to be (a) an amethyst self, (b)
rather thin and uneven Umbrata with a wide but uneven border of the same color
as standards, so lacks I-sub-s, with a thin yellow band around the rim of the
standards and falls, showing as a rose when combined with the amethyst
color. The yellow is almost entirely absent from the beard, which inherits
its blue color from its papa. Needless to say, this is being kept but
used with extreme caution. Those open standards--well, doggy traits don't
seem to get lost easily.
![]() A sib to the above, "R 60-best" is my only
designation so far, shows this color pattern: amethyst-pink color,
tangerine beard with some blue present, Umbrata with the underside of the fall
color showing clearly in one flared up ruffle, narrow but definite band on fall
with the same color as the standards, conspicuously marked hafts typical of many
Umbrata variations.
![]() This may add to the generous contribution by Bill
Burleson, for which I am grateful.
