Cbd Dominant Chemotype

CBD-dominant chemotypes represent cannabis plants where cannabidiol (CBD) concentration exceeds THC levels, a trait increasingly documented in breeding records since the 1990s. Unlike THC-dominant plants, CBD-dominant varieties typically exhibit lower psychoactivity profiles and are commonly associated with specific terpene combinations—often featuring myrcene, caryophyllene, and pinene. Breeders developed these chemotypes through selective crossing of landrace strains and intentional stabilization work, with lineage records frequently reporting Swiss, Italian, and Eastern European heritage in modern cultivars. The CBD-dominant expression is polygenic, meaning multiple genes influence cannabinoid ratios, making stability a key breeding consideration. These plants maintain similar morphology and growth patterns to THC-dominant relatives but require different metabolic pathways for cannabi

Breeders working with CBD-dominant chemotypes focus on stabilizing cannabinoid ratios across generations and identifying which terpene profiles emerge consistently. Selection for high CBD expression while maintaining vigor has become a foundational breeding target in regulated markets.
