    My response-----------

     With apple, and probably many other fruit species, the so-called
"genetic variation
being lost" is a gross misnomer for the following reason(s), or so it
appears to
me.  When the apple left the origin, it did so primarily by seed either by
man or animal.
Somewhere very early in the process, perhaps in as little as 1-2000 years,
the more tasty ones
were preferred and those incredibly few "genes" moved via the silk route to
hybridization (in Great Britian in the 1700s).
     Since then, with the notable exception of M. floribunda 821 crab (the
most effective or active
ventura (scab) resistant gene), most apple varieties available today
(including most antiques)
possess incredibly few gene variations due simply to centuries of
     There are two notable exceptions which come to mind.  One is Sweet 16
which possesses,
among other things, a flavor which is off the chart for apple.  The other
which comes to mind
is Pristine which possesses a leaf design/color which is more akin to
Hawthorne than apple.
I saw perhaps the great, great grandparent of Pristine at the Mycop station
in S. Russia and asked the
curator what it was.  And he said it was a natural hybrid of Hawthorne and
Apple, discovered in
Turkey back in the 30s.  One of Pristine's parents was Camuzat which also is
from Turkey, I think.

     I'm not at all suggesting the germplasm preservation be ignored by
We here in the states have wonderful repositories of near everything.  The
point that I was attempting to make, and obviously not successful, was/is
the near perpetual ranting and raving (at least in my 20 odd years within
about these things so dominate that basic horticultural skills are being
quicker than we think.

     Also, I may add that genetic engineering will never take the place of
breeding or hybridization in my view.  At best, gene splicing will work in
concert with traditional hybridization and may increase human existance
by some 10-12 mins. (on the Kosmic Klock!) at most.
