Caribbean Landraces

Caribbean landraces represent cannabis populations that developed across island and coastal regions of the Caribbean over decades, adapting to tropical climates with high humidity, intense UV exposure, and seasonal rainfall patterns. These open-pollinated cultivars were shaped by local cultivation practices and natural selection rather than formal breeding programs, resulting in genetically diverse seed stock. Lineage records frequently report that Caribbean strains often exhibit sativa-dominant morphology with extended flowering periods suited to equatorial photoperiods. The genetic diversity within these populations has made them valuable germplasm for breeders developing tropical-adapted cultivars and for understanding how cannabis populations respond to humid, cyclical growing environments. Many modern breeding lines trace ancestry to Caribbean genetics, particularly those targeting

Breeders working in tropical adaptation programs regularly incorporate Caribbean landrace genetics to improve mold resistance and photoperiod stability in humid regions. These populations also serve as reference points for studying natural cannabinoid and terpene expression in equatorial environments.
