Although I've tried with the few "ball" type Alliums, such as A. giganteum,
A. jesdianum, A. christoffii, A. schubertii and their possible hybrids
(Lucille Ball, Globemaster, hollandicum, etc), I've never managed to set
seed through intrageneric pollination. I've found all the named cultivars I
have to be sterile.  Of course, this is a limited group!   Is anyone working
with Allium?  I remember a wonderful article in the IBS BULBS on A. flavum

It would be interesting to have a page of hybrids, even without their
parentage!  We do need to assure they are posted as hybrids of unknown
origin to prevent confusion.
