I read a lot about Skagit Valley Gold potatoes. I would also like to try growing them, but the only way for me to get to them is to see them grown from TPS. I would also like to try growing these potatoes (just as an experiment for my own use), but I have not found a source of TPS Skagit Valley Gold anywhere. Tom Wagner no longer sells TPS and I couldn't find anyone else. Are these TPS seeds available somewhere?

You might see if the Open Source Plant Breeding forum has members with it:

Or maybe even Joseph Lofthouse and his fans. I think Joseph Lofthouse has TPS potatoes, but I don't know if he held onto any of his breeding stock. Maybe.

Have you asked Tom Wagner himself? I know his store was down, last I checked, but he has a forum where you can talk to him: https://tatermater.proboards.com

NathanP wrote to me on Tomatoville that Cultivariable is now selling true seeds internationally, not just in the US.
Then I read that it is forbidden to send potato seeds to the Czech Republic - phytosanitary measures. I don't want to break this ban, so I'm giving up an experiment. Damage.
