A landrace is a cannabis cultivar that has evolved over centuries (often millennia) in a specific geographic region with minimal human breeding intervention. Landraces are pure — the result of natural selection in a stable environment. Famous landraces include Hindu Kush (Afghanistan/Pakistan region, heavy indica), Acapulco Gold (Mexico, pure sativa), Durban Poison (South Africa, pure sativa), Panama Red (Central America, sativa), and Thai (Southeast Asia, sativa). Landraces are the genetic foundation of all modern cannabis — every hybrid strain traces its lineage back through multiple generations to one or more landrace parents. Pure landrace genetics are rare in modern commercial cannabis because most cultivators prefer hybrids optimized for potency, yield, and commercial appeal. Specialty seedbanks and preservationist breeders maintain landrace lines.
