Chuck, I find both the MDB and MTB comparisons of
I think something very similar is at work in some
of the variations of the Umbrata spot in BB's and TB's, where we have the
veining and dotting of *I. variegata* plus whatever other genetic elements are
at work giving the wide variety of "butterfly wing" veins. A number of the
products from Tempo Two/Barry Blyth have these beautifully
Among Joe Ghio's work, there have developed a
number with striking veining among those kindred to ROMANTIC EVENING, which,
from its progeny, certainly does have the Umbrata spot in addition to a number
of other significant factors. That Umbrata interacting with other genetics
seems to produce some remarkable patterns, one of which may be evident
in NOTORIOUS and Hamner's CINNAMON SUN, both of which evidently have the
L&S in their genetic makeup.
Whatever it is that accounts for the recently
surfaced "L&S" (line and speckle) pattern observed in PUCCINI,
IMPULSIVE, QUANDARY and several others from Ghio and Keppel, it appears
to interact with the Umbrata spot in a manner somewhat like what you have
observed with the MTB example.
Just to be clear, however, the L&S is
definitely not a plicata allele. That has been tested adequately by both
Keppel and Ghio. It is something distinct.
I'm wondering if it may not be a recently surfaced
allele of the Umbrata spot. I plan to make some additional crosses to
explore this. I do already have one cross between an Umbrata spot
expressed seedling from ROMANTIC EVENING crossed with IMPULSIVE which
should bloom this spring. Sib crosses and back crosses to L&S types
may help clarify the relationship, if any.
