DuPont, Supremes, & Amazons Question
As I understand it, these varieties were produced by chemically treating the plants (?) with colchicine. Or at least doing something to them.
However, I've been reading some older books and it seems that the authors were unaware of this "tinkering" and seem to think it was just a normal mutation. Did the originators keep this a secret? When was it discovered that they had been created artificially, so to speak?
(I've been having fun reading old violet books for free online.) These are the late 40's, early 50's writers and were well-known then so I'm guessing the mystery of these plants was unraveled much later. I believe they are tetraploids, correct?
And, yes, Mrs. DuPont was from Wilmington, Delaware, in case anyone else was wondering if there was a chemical company connection there.
