I've
very recently taken the deep dive into Landrace gardening/Adaptation gardening.
Thanks to Joseph Lofthouse's excellent work in Landrace gardening (and writing
this book about it AND sharing his knowledge about it), AND Hugo's European Telegram group on Adaptation gardening I'm in HappyLand - at last all kinds of questionmarks about why my crops were not thriving are answered and I'm super hopeful about the future! At least I'm having fun

.
To answer the initial questions of this thread:
1) What species are you landracing?
EVERYTHING I can get my hands on from now on. I'm going to apply Landrace gardening principles to all of my growies and see how things develop.
I've semi-consciously been landracing my brassicas and radishes for three years or so, but because I've moved from 670m altitude and 70km more south to 360m altitude and the same 70km more north, the garden situation has changed. Soil is different, climate is different, I suppose I'm different as well
2) What varieties/cultivars of heirlooms/hybrids are you starting with and why?
I'm going to start with the seed bank I've got plus (hopefully) the seed swapping treasures from the Adaptation gardening Telegram group.
3) What will you be selecting for?
* thriving in this climate and on the heavy clay soil
* taste and nutrition values (which I'll just have to estimate energetically/by how it feels in my body)
* ultimately I'd love for the plants to go to seed and self-replicate on spot in their companion planting situation. So in a way, making annual and bi-annual plant guilds perennial by ... neglect?
4) What is your location/growing conditions?
Central France, mellow-ish climate due to many natural pools, ponds and some lakes in the surroundings (we've established two ponds as well), heavy clay soil, old orchard, a part of which used to be horse pasture a veeery long time ago (45-55 years ago?). Indication plants: nettles, sheep sorrel, creeping buttercup.
