When you are using AB as one parent you are now talking of something
entirely different. Consider the AB as a plicata in this cross.

Basically when you cross an AB with a plicata you seem to end up with a
high number of plicata look a likes. For example, the iris Walker
Ross from a cross of an AB X Spinning Wheel. There are a good number of
examples of this

Of course this works for some AB and not for others.

BC seems to needs the recessive plicata as base to put the BC pattern
on top. So most the large majority of BC need to have a plant with
four plicata genes. doesn't seem to matter which plicat alleles it is.

Other combinations could work as well, and have worked. But a long
shot. If you have lots of space and time to grow speculative seedlings,
go for it. You could get lucky. Also buy some lottery tickets.

I wonder if the BC isn't stronger somehow, though. Using BC and plic
as pod parents using AB pollen has given some BC pattern on 100% of the
BC parent offspring. Using the plic parent has given some BC patterns
as well, but has never given a hint of a straightforward plic pattern
in the results. There are not huge numbers of seedlings here, but
there have been more plic parent seedlings grown than those using a BC
parent. Presumably the TB chromosomes are pairing with the TB material
from the AB parent. I wouldn't have expected so many to have shown the
broken color pattern. Mary Lou should give it a try and see :). Nice
looking seedling to work with.
