Re: Reverse polyploidy?
Hapoid inducers are generally plant genotypes that can be used as a male
parent in a cross but cannot fertilize the egg of the female parent.
However, in some limited cases the egg is stimulated to go through mitosis
to form a haploid embryo.

Thanks, it's always nice to know that one's hunches are in the ballpark.

With bamboo that may not flower for 50 - 100 years? Sorry, I'm already 51,
I don't have the time. 8>
However, what are "haploid inducers?" New term to me...
