[nafex] Crab apple disease resistance

This answer a long time question. When Rocky Meadows was in business I 
noticed one year a variety was listed as a crab  and as a regular apple the 
next.
A native Iowa crab is on my property and when I grafted a commercial variety 
the top out grew the crab and eventually fell over.

By definition, a "crab apple" is any variety bearing small fruit, less than 
2-1/4" diameter. "Crab" says nothing of the species or flavor.
