Cbd Dominance

CBD dominance refers to cannabis cultivars bred to express higher cannabidiol (CBD) concentrations relative to THC, typically resulting in CBD:THC ratios of 1:1 or greater, sometimes reaching 20:1 or higher. This phenotype emerged from intentional breeding programs beginning in the early 2000s, combining genetics from hemp-derived CBD-rich strains with cannabis cultivars. Breeders working in this category often cross high-CBD phenotypes repeatedly to stabilize the trait across generations. CBD-dominant plants don't necessarily have a distinctive aroma profile—terpene expression varies widely depending on parent genetics. Lineage records frequently report that many CBD-dominant cultivars derive from Swiss, Dutch, or Canadian breeding stock selected for this cannabinoid ratio rather than for specific volatile compounds.

Breeders targeting CBD dominance prioritize cannabinoid ratios in selection criteria, often using laboratory testing (HPLC/GC-MS) to identify and stabilize high-CBD phenotypes across breeding cycles. This focus on cannabinoid content over terpene expression has created distinct cultivar families used as parent material for commercial and research programs.
