Postman is at the National Clonal Germplasm Repository in Corvallis, OR, and
that is where all the plants are kept in inventory and grown out.  These
crosses come from others, I gather, and the repository archives them.
Shipova, the pyrus X sorbus has been in the market for some time.  There is
another pyrus X sorbus, but I can't remember its name, and it is at the

The quince (cydonia) crosses with pears result in pyronia veitchii, also a
plant that is wide-spread.  I remember reading that it was developed in
either France or Germany.  There are a couple more pyrus X cydonias, too.

The only samples Postman had were the pyrus X sorbus cross, which some
people on this list have identified as Shipova.  I've emailed Postman to ask
the cultivar name and will pass it along when he responds.
