South American Populations

South American cannabis populations represent landraces and traditional cultivars developed across diverse climates spanning the Andes, Amazon basin, and coastal regions. These populations evolved under varied altitude, humidity, and photoperiod conditions, resulting in distinct morphological and chemical profiles often adapted to equatorial and tropical growing zones. Genetic records and breeder documentation frequently reference Colombian, Peruvian, Brazilian, and Ecuadorian origin populations as foundational germplasm. South American genetics are commonly associated with sativa-dominant architecture, extended flowering cycles, and terpene profiles shaped by high UV exposure and humid environments. Historical seed trade and regional cultivation practices have created overlapping populations with significant genetic diversity within and between countries. These populations remain import

Breeders working with South American populations often select for extended vegetative vigor, delayed maturation timing suitable for long growing seasons, and disease resistance developed under high-humidity conditions. Introgression of these genetics into modern hybrids is pursued to recover sativa characteristics, improve tropical climate adaptation, and diversify terpene and cannabinoid expressi
