Regional Selections

Regional Selections refers to cannabis populations that have been cultivated and refined within specific geographic areas, developing distinct characteristics suited to local growing conditions and breeding priorities. These selections emerge through multiple generations of cultivation in a particular climate or region, allowing plants to express traits aligned with environmental pressures and breeder preferences in that area. Lineage records frequently report that regional selections carry genetic signatures reflecting their origin—whether from specific valleys, altitudes, or climatic zones—which can influence plant structure, maturation timing, and terpene expression. Breeders working in traditional cannabis cultivation regions often maintain regional selections as foundational genetics, using them as parent stock to preserve locally-adapted traits or cross them with other populations.

Breeders use regional selections as reference populations to maintain genetic diversity, preserve locally-adapted vigor, and establish baselines for understanding how environment and selection pressure shape cannabinoid and terpene development. Regional selections also serve as crucial bridges between traditional landrace genetics and modern hybrid development.
