https://m.youtube.com/watch?v=xdsg2NSPZ0wI was working and couldn't attend this but here is the video looks like. It is a eorganic carrot breeding seminar about an hour and 37 minutes long.
I haven't watched it yet.
My own attempts at carrot breeding would be extinct if not for volunteers. It strikes me as a limited grex. I also have Joseph's carrot landrace which I grew for seed for snake river last year and which is also a component of my own volunteering grex.
