"If it is a sport, how does one treat it in classifying it. What is a
sport effectively? Have there been other sports and how were they treated in the
realm of registrations? Can someone throw light on this?"
There have been a number of sports registered, such
as those that originate from Honorabile, including Kalidoscope (which may or may
not be identical to "Joseph's Coat"--originally an alternate name, but I've been
told there are clones circulating where each of the two names is attached
to distinctively different cv's).
One sport I know of was used in Schreiner
red-bearded white breeding and simply dubbed
"white sport of May Hall" and not registered or
offered for sale.
I posted a note about sports on Iris-talk (I think)
that will be reprinted in the Spring Tall Talk with a few minor changes.
For that reason I don't feel free to copy the text here. The
essence of it, however, is that a "sport" is a genetic variant of a cv, arising
not from seed but from a scion or division from the original, is stable and
distinct from the original in some manner.
I had a plicata sport once from CLARA NOYES.
Clara herself had a butterfly-wing veined pattern all over the fall.
I was very careful to check when I dug and divided. The bloomstalk of the
plicata arose from a rhizome that broke off from a rhizome of the
normal Clara Noyes.
As to "William Mohr Giant" the assertion that
fertile pollen was produced at times did not lead to any registered progeny as
far as I know. Fertility would NOT occur in a diploid (onco x diploid TB)
in any form other than by fertilization of unreduced gametes, which Wm Mohr did
rarely produce. The number of pollenizations made to get the fairly good
number of offspring must have been astronomical. I know that I made many,
many attempts and never got any seeds. "William Mohr Giant" showing
fertility says to me that it could NOT be a sport---the chromosome count
would have had to be doubled for fertile pollen to be produced--ever. To
get a doubled-chromosome William Mohr would have required very tightly
controlled application of colchicine or one of the herbicides that had not been
yet developed in 1951. I know of no occurances of doubled chromosomes
occuring other than with very tiny seedlings, such as Orville Fay, Dr. McEwen
and such people have used with various plants--hems, Siberians, LA's (Kevin
Vaughn) and JI's. No published work that I know of describes
techniques for use with adult plants. I only wish there were--and we had
doubled, fertile OYEZ or some other of the diploid hybrids of the same type as
William Mohr that came from the early work of C. G. White. For such an
occurance to occur spontaneously boggles the imagination.
Close inspection of the beard in the photo of
"William Mohr Giant" suggests a flower 3/4 tall bearded to me. I
believe the form and pattern displayed also resembles a "Mohr" more closely
than it does the original William Mohr. Let me add I speak from vast
ignorance and large opinion without much humility attached.
