HYB: 201 Homework -- Signals
I processed hundreds of seeds
from SOSTENIQUE X TRIBE OF
JUDAH, but kept complete records
on only those that survived the
second selection cycle.
Mortality is high among 1/4-bred
seedlings. I suspect many would
not even have germinated under
natural planting conditions, but I =
know that some succumbed while
still under lights and others did not
survive their first year in seedling =
In summary, there were enough to
show a wide degree of variation but
there are undoubtedly other strange
combinations that could show up in
a larger sample.
Signal inheritance is quite complex,
so we've pretty much glossed over
that part. Rather than assign
"homework" on this trait, I'll go =
ahead and share my observations.
This group of seedlings can be
divided into three signal types: solid, =
stippled, and camouflaged.
The solid type was enough rarer than
the stippled one to make me suspect
that there more than one modifier
involved. As a whole, observations of
these seedlings do not support the =
model of a simple allelic series. Although
there are some distinctly solid signals
and some markedly stippled ones, they
fall along a continuum so that there
are also some that require close
observation to classify. =
Camouflaged signals came in both
types -- just so little contrast between
signal and fall that it took a close look
to identify the signal. Those were
quickly culled. =
The lesson here is that TRIBE OF
JUDAH can pass good signals on
to its offspring, when mated with the =
right TB and SOSTENIQUE does =
allow aril traits to show through so
is worth using with other arilbreds.
Yes. I've tried both with other partners
and am quite pleased with the results.
More to come....
