Hi Michael,

Thanks for the note.  I probably should have worded my question 
a little better.  The intent was that since it was assumed that 
the tree is monoecious and produced both male and female flowers 
the desired trait of non-bearing could presumably be the result of a defect 
in the female flowers while the male flower could still potentially produce viable 
pollen and not effect the desired trait.

Monoecious just means that the male and female flowers
of a plant are separated instead of having perfect
flowers with both parts.  A monoecious plant will
still produce both male and female flowers, they will
just be separate.  If it were dioecious, then male and
female flowers would be born on separate plants.  

To answer your question, I'm not sure if there are any
nonbearing clones out there.
