I'm wanting to grow potatoes that don't have any genes for cytoplasmic male sterility. In other words, I'm wanting potatoes that fruit like tomatoes (they actually do exist), productively, so I can grow them from seeds instead of tubers.

I know you can buy Zolushka potato seeds (TTS: true potato seed—not the same thing as seed potatoes) at Park Seed. However, I don't know if the resulting plants have a chance of having cytoplasmic male sterility or not. Do they? Do they fruit? That's my question. I mean, buying the seeds is worth much more to me if I can save my own seeds every season or two.

Additionally, if you know where I can get some other kinds of TTS that don't carry a cytoplasmic male sterility gene, feel free to let me know. I see that Joseph Lofthouse has a landrace he's working on, with TTS. I don't know if he sells seeds, though, but I could ask him. It sounds promising, anyway.
