Southeast Asian Landrace

Southeast Asian landraces represent cannabis populations that have adapted to tropical and subtropical climates across regions including Thailand, Laos, Cambodia, and southern India over centuries of informal cultivation. These varieties are typically sativa-dominant, with tall plant structures, long flowering periods suited to equatorial photoperiods, and often display lime-green or yellow-green coloration. Lineage records frequently report these genetics as foundational to modern tropical and equatorial-adapted breeding programs. Southeast Asian landraces contributed substantially to global cannabis diversity, particularly influencing Thai stick culture and modern sativa-leaning hybrids. Breeders value these populations for their climate resilience, vigor, and potential for long-season outdoor cultivation in warm regions.

Modern breeders working in tropical and equatorial environments often incorporate Southeast Asian landrace genetics to enhance photoperiod-adaptive traits and heat tolerance. These populations serve as genetic reservoirs for sativa characteristics and breeding programs targeting extended-season cultivation.
