Hello all, I had the opportunity to visit the TGRC greenhouses in Davis, CA the second week of Februrary. I took some pictures, but they kind of suck due to my phone. It was very interesting trip and they were doing some increases on some different types. I believe that this is a pimpinellifoliym. Attachments:

I am envious. Post what you can as far as pictures go, but let us know a little more about the experience.

Hello again,
sorry for my tardiness. I have been travelling and busy with work. Basically we got a short presentation about TGRC. They house mutants, genetic stock and wild species. They increase around 80 lines a year with about 50 plants/line. Basic focus is on the biotic tollerance genes, disease resistance genes and novel trait genes.
Introgression Lines were an interesting part of the tour. Basically an IL is a tomato line that has a portion of a chromosome or whole chromosome from a wild line. This makes it easier to bring in the wild stuff into the cultivated lines.
I have a handout that I need to scan and get up here. It has a listing of the species, geographic distribution, ease of crossing to cultivated tomato, fruit color, disease resistance and "other traits". Also new and old taxonomy, flowering time, mating system, pollination method and ways to get seed to germinate better.
Thanks
Jonny
more pictures to follow. also i need to get to my scanner to scan this sheet. should have that by weekend.

This one is from the Atacama desert in Chile. It is S. sitiens. I guess the have issues watering it and have to use rootstock so that they can get some fruit. Attachments:

This one had fragrant flowers. They mentioned it is the only tomato with fragrant flowers. They didn't smell good, but they didn't smell bad either. Attachments:

Here is one of their cards that shows how they do things and i.d. everything. This one is a mass sib (pollination method), done on 4 different dates, it is S. arcanum (old L. peruvianum), it was collected in Peru Attachments:
