What you have written is a major issue for breeding, but has exisited since
long before transgenics, and has not been forgotten. The lessons learned
with blight in corn and phylloxera in grapes are taught in every breeding
course. The loss of thousands of apple varieties occurred well before we
even knew  that transgenic crops were even possible.  For the proponents,
an attractive feature of GE is that the list of varieties need not be
reduced further; you can easily transform 10 or more (and in fact, more
than 10 varieties of potatoes and dozens for cotton, corn and soybeans have
already been done).

By the way, the original resistance to phylloxera came from US wild grape
root stocks, based on the suggestion of the American entomologist Charles
Valentine Riley in the mid-1800's.
