High Cbd Landraces

High-CBD landrace populations represent cannabis genetics that evolved in specific geographic regions with naturally elevated cannabidiol expression, often without intentional human selection for this trait. These landraces—including varieties from Nepal, Lebanon, and parts of Southeast Asia—frequently exhibit CBD-to-THC ratios that range considerably within populations, reflecting adaptation to local environmental pressures rather than selective breeding. Historical records and phytochemical analysis suggest these landraces emerged through centuries of cultivation in regions where diverse cannabinoid profiles may have provided agronomic or ecological advantages. Modern breeders studying high-CBD landraces examine them as source material for understanding cannabinoid biosynthesis pathways and for developing stable, CBD-forward cultivars through controlled crossing.

High-CBD landraces serve as foundational genetics for breeders developing CBD-dominant and balanced-ratio lines. By crossing landrace material with stabilized modern cultivars, breeders can document how cannabinoid expression segregates and identify markers for consistent CBD production across generations.
