I have now been direct seeding tomatoes for three years inspired by a few volunteers that made just a few ripe fruits in 2016. I have also been growing wild and wild hybrid tomatoes for the last three years.
Goal 1: Direct Seeded Tomatoes, this is looking very doable and I will be growing out an F3 population of at least one variety bred under these conditions. It is descended from Blue Ambrosia and Amurski Tigr both of which work for me direct seeded and I am tentatively calling it Exserted Tiger.
Goal 2: Selecting for exserted stigmas
Goal 3: Tasty self incompatible tomatoes short enough season to direct seed. Will be working on the tasty part this year and not so much the direct seeding part. Though I may manage to grow enough seed this year of the F2 population I am growing out this year to try direct seeding the F3 next year. I do have enough seed of other wild hybrids to potentially direct seed this year if I have space. This goal of my project is a subset of a larger project Joseph Lofthouse is doing to develop self incompatible tomatoes.
Goal 4: Dry Farming, I never watered my main patch last year. It did rain regularly though and unusually so it wasn't a good test. However, it seems possible that this might be a very achievable goal here.

Have been saving a lot of seeds. Pictured is some variation that segregated from a Golden Tressette that had a blue blush last year. Also one putative cross. Much of garden got frosted but still have some. Saving tomato seeds as fast as I can.
The main population for 2020 is G2 plants of Big Hill x W? Including some fresh seeds Joseph sent of Big Hill x WXL and Big Hill x Wbest of 2019 mix. Though also growing multiple 72 cell trays of Big Hill x W4 from the 13 plants I grew out in 2019 all of which had boringly wild type fruits and seemed to all be habrochaites crosses but also all seemed to be one copy carriers of the obligate out crossing gene based on their dropped flowers. There will be a very good chance to get some tasty fruit this year. I am liable to direct seed a row or two adjacent to keep the direct seeding in the project. I will grow a few odds and ends domestics with this as well as pollen flow is unidirectional with the obligately out crossing populations.
Population two is some plants not ready for prime time. So they are taking an isolation slot. Including a couple populations one penellii the other habrochaites that are about 75% wild with with wild ancestor as the cytoplasm mother. Joseph has a thought that these may not accept pollen that is S broken. So no recessive selfing genes here. However also expected to be pretty wild and unpalatable so far.
Population three is my hope that one peruvianum grown with penellii will accept penellii pollen. The latest iteration of my hope to get peruvianum into a cross. This will be the smallest population.
Populations four and five will be F3 domestic exserteds one I am calling exserted tiger and the other exserted orange hill.
Population six is a contract grow out not in the project. It will get a prime spot, which I think will not be the one originally envisioned.
Population 7 will be a pure Big Hill grow out for seed. A Joseph Lofthouse bred domestic with exserted stigma on a easy to work with beefsteak flower.
I've been following Jospeh Lofthouse's plant breeding efforts for a couple of years now, especially his great work with tomatoes and squashes. I'm in Western Oregon, growing without irrigation using seeds I got from him in 2018, and saving seed particularly from open-flowering tomatoes. I would be interested in exchanging seeds with others who are growing open-flowering tomatoes and genetically diverse short-season tomatoes in any climate.
