Old World Cannabis Genetics

Old World Cannabis Genetics refers to landrace and heirloom cultivars originating from traditional cannabis-growing regions—primarily Africa, the Middle East, Central Asia, and the Indian subcontinent—where cannabis has been cultivated for centuries. These genetics are characterized by their adaptation to specific climates, soil conditions, and local cultivation practices, often resulting in distinct aromatic and morphological profiles. Breeders and geneticists study Old World genetics to understand baseline cannabinoid and terpene expression before modern hybridization. Preservation of these lineages is considered important for maintaining genetic diversity within cannabis breeding programs. Many contemporary strains carry Old World ancestry, though pure landraces are increasingly rare in commercial cultivation.

Breeders incorporate Old World genetics to introduce climate resilience, distinctive terpene profiles, and landrace vigor into modern cultivars. These lineages serve as reference points for understanding cannabinoid inheritance and for developing regionally adapted breeding populations.
