Which P. Nigra? From where? Any from anywhere? Isn't that a little general? I'd trust a specific strain from a specific location - to try.

I believe what Rick Sawatsky was talking about was using wild or "pure" p. nigra. The ironic thing is that nowadays there are very little pure sources left, rootstocks of supposed p. nigra are a couple of generations away from the pure p. nigra. The moral of the story is the more pure the source of p. nigra, the better chance it will have of successfully pollinizing p. nigra or p. americana hybrids. I would have to ask, but I assume that pollen from pure p. americana would be a good source as well.

As mentioned in the article, hardy P. salicina hybrids from manchuria such as Ptitsen #3, or #5, Fofenhoff, Ivanovka are also good pollinizers. I don't know if these selections are widely available in the US, however.

South Dakota is supposedly a Japanese x american (p. salicina x p. americana) hybrid, so based on the article, probably would not be a good pollinizer. The Toka and it's sister Kahinta plums are p. americana x p. simonii hybrids I believe, which may be good pollinizers to the p. salicina hybrids.
