This is what I do mostly.  I get seeds, but germination has been less than
satisfactory.  Also, it probably would be well to bear in mind what you get
with such a cross.  More than half the contributing genes are likely to be
from the TB side.  The result of that imbalance is as likely as not to yield
a plant that looks more like a TB than an AB, but without some of the
considered desirable traits that TBs possess.  E.g., less branching, lower
bud counts and possibly more temperamental growth habits.  One arilbred
breeder I talked to once described them as mostly 'inferior TBs'.  Not only
that, the fertility of the resulting plant is diminished to non-existent.
That makes them harder to use in subsequent generations.  I've found so far
that this genotype is difficult to cross with another of the same genotype.

I still think it's a worthwhile endeavor - at least so far I haven't given
up on the project.  I hope to get plants that display enough fertility to
use them with other ABs and to see if I can achieve plants with durable,
strong growth habits that display a good bit of the aril ancestry in the
look of the bloom.  I'm not too concerned with increased bud counts, though
a bit more branching might be nice with the resulting extra blooms that
would provide.  I definitely am NOT trying to create TBs with aril markings,
patterns or form.  I would like very much to have some of the durability in
plant growth that TBs display.

It's fun.  I do it for my own enjoyment.  Not too likely I'll ever achieve
anything wonderfully great and even less likely I'd be able to recognize it
if I did.  You can certainly get the crosses, but what are your hopes and
aims?  What would you enjoy?  I plan and expect to grow a whole lot of
disposable iris and have fun doing it and maybe learn some things in the
process.
