    Where can one get the corrected text for registered hostas you speak of
in the below message? In the past we could see the corrections in the latest
AHS Registration publication. This is no longer available.

> RE:>>Rather it should use "(pod parent) Seedling", which would mean
"possible hybrid".
> Excellent point.
> It should be fairly simple to determine whether an "Unknown Hybrid" was,
in fact, an Hybrid with an unknown pollen parent or a plant that has been
selfed.   A simple DNA weighting analysis, via flow cytometry, could verify
whether the F1 was an outcross or self-pollinated.   Ben Z. had indicated a
while back that he would perform such a test at N/C, if the plant were
shipped to Leiden.  I have stated that if the timing is right, I would do so
for $11, with prior arrangement.
> Of course, the motivation to perform the test is low (for many
hybridizers) so the listing of "Unknown Hybrid" will forever be assigned to
that cultivar, at least on the printed page.  It's good that the errata gets
published, and my hat is off to Kevin and all of the AHS registration
authorities for helping to make this happen, yet the likelihood of that
information being transferred to the main entry page in each or our
registration books is quite slim.  I believe Marvin Lemke does this, but
does anyone else?
> Such questions need to be resolved prior to the plant being registered,
> Fortunately, In another 100 years (or 10?), the registrar will have a
specialized piece of assaying gear with which he/she can sample the plant's
molecular ID.  The DNA weight and various sequencing data will be obtained,
verifying claims of the registrant--perhaps some species lineage info as
well as confirming parentage.
> The sequencing test would be as simple as that done for paternity tests on
humans. This will be a service provided by the registrar, for a nominal
surcharge.  All plants being registered would go through this ID'ing
> Thus, if someone sends in a leaf that they claim was an hybrid, yet the
DNA weighting is 22.5pg and the pod parent DNA weight was 22.5 pg, the
registrar would request more information prior to authorizing the
registration.   This type of result would lead one to believe, and the hunch
would be highly probable, that the registrant  is under the wrong impression
about the pollen parent.
> Fortunately, the entire Hosta genome will have been sequenced and it will
be much simpler to ascertain parentage.    All we have to do is wait for
that 100 years to pass ...
> The practical benefits from obtaining such data even NOW should be
self-evident.   Perhaps Ben Zonneveld will comment on this, or already has?
> We could, of course, begin adding DNA weight datum to the registration
database NOW, for currently assayed plants.  Easy?  No.  Important?  Yes.
Otherwise, we'll continue to believe such plants as H. 'Hirao Tetra' are
tetraploid for decades when it has been shown to be otherwise.
> Errors in the taxonomic identification process inhibit Hybridizers in
their pursuit of controling the production of higher quality cultivars,
which is the goal of serious Hybridizers.

> The Scientific Speaker time slot is for Wednesday, at 5:00-6:00PM--Shelby
room.  Don't know the format or whom it is that will speak.  However, any
interested party can "talk science" in MY garden anytime from 8:30AM-4:00PM
on Wednesday, or 7:30 AM until 2:00PM on Sunday, or when we bump into each
other at the convention.
