Cannabidiol Dominant

Cannabidiol-dominant (CBD-dominant) strains are cannabis cultivars bred to express notably higher concentrations of cannabidiol relative to tetrahydrocannabinol (THC). These genetics emerged in the early 2000s through intentional selection and backcrossing programs targeting CBD-producing phenotypes, often incorporating landrace or high-CBD cultivars like Harle-Tsu, Charlotte's Web, and Cannatonic founder lines. Breeders working in this category typically employ marker-assisted selection and progeny testing to stabilize CBD expression across generations. CBD-dominant genetics are classified by cannabinoid ratio rather than morphology, though cultivars within this family often exhibit variable growth patterns depending on their underlying genetic backgrounds. Lineage records frequently report these strains as hybrids incorporating Indica, Sativa, and Ruderalis ancestry.

Breeders use CBD-dominant lines as donor parents to introduce or amplify cannabidiol expression in commercial and research programs. These genetics serve as foundational material for stabilizing 1:1 THC:CBD ratios and higher-CBD phenotypes in F1 hybrids and inbred lines.
