What is preservation breeding?

Preservation breeding is the disciplined work of keeping rare cannabis genetics alive — landraces, heritage cuts, founding cultivars, irreplaceable working lines. The output is not a new strain. The output is continuity.

Methods vary: tissue culture maintains living material in pathogen-clean conditions indefinitely; seed production captures the genetic profile in storable form (slowly drifting with each generation); archival cultivation keeps mother plants alive for clone supply.

Why it matters: cannabis genetics are extraordinarily fragile. A flood, fire, contamination event, or grower attrition can erase a line forever. Hindu Kush populations have been actively diluted by imported hybrids for 50+ years. Famous clone-only cuts (Forum, Sherb, Triangle, Ghost) survive because someone, somewhere, kept them alive.

CannaForge's TC Preservation Program is an institutional layer for this work — tissue-culture cold-storage for cultivars that matter, with public attribution and breeder-of-record permanence.
