HYB: 201 Homework -- Signals

I processed hundreds of seeds
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 =

beds.  =

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....
