In the lead article of the most recent edition of Compact Fruit Tree,
the publication of the International Dwarf Fruit Tree Association, the
authors indicate the advantages of G-16 over M 9 are better fireblight
resistance and slightly better yield. The downside is the extreme
sensitivity to latent viruses in the grafted scion which can abruptly kill
the tree. I have had that happen here in Houston. Thus, grafted wood must
be virus free. They also claim that it is not yet clear if G-16 is cold
hardy.
