- Yep, they qualify - allopolyploids (as they are called) are valid species.
- In fact all of the standard 'breeds' of wheat are members of artificially bred
- species. The most common types of wheat grown today are hexaploids (twice
- hybridized), but even most of the tetraploid wheats are artifically produced
- (thought there *are* a few natural tetraploid wheats, I believe).
-
- I forget the species names for the domestic wheat species.

-
- There was one claim for breeding a new species of Drosophila, but closer study
- showed that the experiment had started with an undiagnosed pair of sibling
- species.
