Old World Cannabis

Old World Cannabis refers to cannabis varieties with documented or presumed origins in traditional growing regions of Asia, the Middle East, North Africa, and Central Asia—areas where cannabis cultivation spans centuries or millennia. These genetics are distinguished by adaptation to specific climates, altitudes, and photoperiod conditions in their regions of origin, rather than by modern breeding interventions. Lineage records and seed-bank documentation often trace Old World strains to landrace populations or heritage cultivars preserved through informal seed-saving practices. The term serves as a classification tool for breeders and geneticists studying genetic diversity, regional adaptation, and historical cannabis botany. Old World genetics frequently appear as parental lines in contemporary hybrid breeding programs seeking to introduce climate resilience or specific terpene profile

Breeders working in preservation and biodiversity projects frequently incorporate Old World genetics to map genetic markers associated with regional adaptation traits—such as photoperiod sensitivity, disease resistance, or terpene expression—that may have been selected informally over generations. These foundational genetics also serve as reference points for understanding how modern cultivars div
