Traditional Cultivation Regions

Traditional cultivation regions refer to geographic areas with established histories of cannabis breeding and production, where landrace genetics developed under specific environmental pressures. These regions—including the Hindu Kush, the Fertile Crescent, Southeast Asia, and parts of southern Africa—produced distinct plant populations adapted to local climate, altitude, and photoperiod conditions. Breeders studying traditional region genetics examine how environmental selection shaped morphology, flowering time, and terpene profiles over generations. Modern breeding programs often incorporate landraces from these regions to introduce genetic diversity and climate resilience. Understanding traditional cultivation zones helps breeders document genetic heritage and predict trait expression in new environments.

Breeders working with traditional region genetics use them as foundation stock to study environmental adaptation and to introduce locally-proven traits into commercial crosses. Landraces from distinct regions provide reference points for understanding how geography shapes plant development and cannabinoid/terpene expression.
