You're addressing a question I've long been curious about - what is the
relationship between genera Aronia, Pyrus, Sorbus, and Crataegus (and select
others)? Aronia and Pyrus will graft; Pyrus and sorbus will cross; Aronia x
Prunifolia is classified in genera Crataegus, Mespilus, Photinia, and Pyrus,
depending on source; Crataegus, Sorbus, and Mespilus will cross...
I still await DNA testing for further definition. As many of you know,
botanical species are classified by characteristics of the flowers, which
assumes a definitive correlation between genetics and floral
characteristics. That assumption does often work out, but is not by any
means exact. Fifteen years ago I was somewhat keeping track of efforts to
use genetic testing to reclassify plants. The zoologists are certainly
making strides in genetic studies, but I haven't heard about botanical
reclassification in some time.
News and comments appreciated...

I has anyone else used Aronia as a rootstock for
anything else? What is it comapatable with?
