huge difference. With Canadian Streaker there can be very large
differences between plants and selection certainly was necessary to
help increase the amount of streaking. The same thing with other
variagated foliage plants. Why not the same thing with plb. It could
be much the same thing, a factor in the endosperm rather thenin the
genes.

Plf con be passed by pod or pollen parent I have been working
with this for some time. It is a ressive gene and dosen't express
its self in a heterozygous form it does vary in its expression.
I think in a 2 dose it's light,3 dose it's darker,& 4 dose if in
fact that has been done would be the darkest homozygous.I have one
Seedling the plb is streaked but not the foliage.
