Maybe it would work if characteristics could rub off on adjacent plants! :)

Yes, if two species will not cross, but  will cross w/a third species, it
could possibly be used as a bridge to get genetic material from one to the
other. For example: If A and B will not cross, but both cross with C, then
you could cross A or B with C and the resulting hybrid might cross w/the
species not yet used.

Such as: were both crossed with a zonal (I know nothing of the > exact

Zonals have large chromosomes, while the two species mentioned have small
chromosomes. According to Dr. Mary Gibby,(U.K.) it would be a bigger hurdle
to cross species w/ different chromosome sizes, than it would be to cross two
species w/ the same chromosome size but different chromosome numbers.
