I am working on getting the landrace seeds from here. I have two different sources. Both are lifelong growers, both told me they have them. One told me that the last harvest they ran of landrace was last year, so the seeds will only be a year old.
About 10 years ago I went to India for a few months. I found and brought back landrace seeds. I sent them to Dr. Chronic seed bank to give away as freebies. A few hundred at least.
