    Old landrace populations like Durban or Thai lines only survive if people keep growing them as open pollinated regular seed. A single feminized cutting is a dead end for the gene pool, since it freezes one plant and drops everything else in the population. Several preservation projects and their seed sources are listed on https://breederregularseeds.com, along with notes on minimum population sizes to avoid bottlenecks. Twenty plants per generation is roughly the floor before you start losing diversity.
