I think I met Steve Peters about 5 or 6 years ago. He came up with OSA for a free workshop as part of some extended OSA support for the local seed movement here in Western Montana.
I've been following Fred Hempel Artisan Seeds on Instagram. Recently he posted the following. "We are devoting a corner of our field to the work of Kanti Rawal and Steve Peters (Seed rEvolution Now) this year. They are developing new low input, hardy tomato varieties that don't require staking."

They are dry farming them in California and they don't require staking. They are supposed to be modern determinates crossed with heirlooms.
I wondered if they might be dwarfs but uncertain if that is actually the case- there are tomatoes other than dwarfs that do a decent job of keeping the tomatoes off the ground. In fact Joseph Lofthouse wrote about that with some of his older strains.
Anyway, I think it is fun that there are groups of tomato breeders out there that I haven't heard much of before but who are doing very interesting work!
