No. It involved two species of grains, but after 20 some years I don't remember
the details!
: Pushing for more more more...What kind of speculation?
1. Are any chromosomes from different species so nearly homologous that they
could pair and cross during meiosis, yet still produce a viable chromosome?
2. If so, could this not produce advanced-generation multi-species hybrids
that are, for all practical purposes, a new type of autoploid?
3. If so, is it not possible to obtain cultivars that are predominantly of
one species, yet have a trait not normally found in that species.
Example: a dominant amoena many generations removed from PROGENITOR. Does it
carry a complete set of chromosomes from I. reichenbachii/suaveolens? Or just
the chromosome on which the dominant amoena gene resides? Or just a fragment of
that chromosome "injected" into the effectively homologous chromosome of another
species like I. mesopotamica?
