Re: HYB: umbrata

Chuck Chapman (who I can't seem to talk into signing his posts <g>
<---I would classify the following as having the umbrata pattern.
Wabash, Ringo, Escatic Echo, Magic Man, Magharee, Outrageous Fortune,
Bristo Magic, Latin Lady, Viva La France, Sweeter than Wine, Crimson
Snow, So Fine, Spin Off, Heavenly Body, Impressionist, etc. Some have
more of an edge then others (pun intended) with Escatic Echo being
particularly dramatic. The restriction of pigment from the edge seems
to mostly effect the anthocyanin pigments but can effect both
anthocyanin and carotine pigments.>

Oh goodie - more pedigrees to look up! <g>  Anybody know if these have a
common ancestor with the umbrata pattern?

I am always more interested in ancestors than recent introductions
because of the dreadful growing conditions here.  If I can identify
relatives that are older and cheaper, but still carry the same pattern
genes, and have been around long enough for folks to know whether or not
they will do well under stress, then I am more willing to invest in the
more recent 'better' offspring.

The umbrata pattern looks almost like a 'negative' of the plicata
pattern, so much so that it made me wonder if there could be a mechanism
where another allele might be interacting with it in some wacko way that
inhibited the inhibitor of anthocyanins and inhibited the anthocyanins
on the rim.  But I guess that doesn't make much sense (if it did in the
first place!) if carotene pigments can also be umbratas (pink or orange
with white rim?).
