I grew a patch of Solanum peruvianum again this year. I was able to add a couple more accessions to the patch. I allowed them to promiscuously cross pollinate, and collected the seeds in bulk. I didn't do any sort of selection on them. There was a late/hard frost that killed many plants. Other than that, they grew fine.
I planted one S. habrochaites plant on the edge of the patch. It did not set any fruits, even though it flowered all summer long. Leads me to believe that the two species are pretty far apart genetically.
I'm seeing more types of pollinators on the wild tomato flowers...
