Hi. A Cannabis line is not preserved by only a handful of plants. But Western growers cannot do much more than get some seeds, usually no much more than 10 or 20, and grow as many plants as one can do which usually they are no more than 20 or 30 at best. The problem is that most people chop all the males, and someone that wants seeds leave only one.
In my neck of the woods young people prefer hyped Kush dominant polyhybrids, or even worse, dwarf autoflowering hybrids. If you offer seeds to them they ask if those seeds are feminised and if they aren't they usually avoid them as hell. Here none have enough patience to finish a good Thai.

The primary goal of a germplasm preservation project is the conservation of the entire gene pool. It is very important that the population size is large enough to ensure that nearly all of the genes within the gene pool are reproduced in the resultant seed. We have set a minimum limit of 1,000 plants in each population. This should ensure 99% preservation of the gene pool. The second goal is to reproduce the accession in sufficient amounts to distribute seed to researchers worldwide. We have set a minimum limit of 200 grams of seed for storage and later reproductions. Two hundred grams is approximately 10,000 seeds and will allow 5,000 seeds to be stored in an active collection for reproduction and 5,000 seeds to be kept in long-term storage. Seeds can only be released to the research community if more than 200 grams of seed from each accession are held by the VIR.
