I think that a central part of the meaning of "landrace" is that it developed from a very diverse gene pool.
Just one variety of plant would not have a great deal of genetic variety. Both OP and hybrid cultivars come from inbred lines that are as genetically uniform as their breeders could make them.
ATP is lucky to have
@Joseph as a member. He is breeding multiple landraces using the widest possible variety of cultivars as his source gene pool.
His climate selects ruthlessly and his yields increased greatly the first few years he combined many cultivars and kept only those plants that survived his weather.
Joseph also has a landrace blog with the Mother earth news:
