Cbd Type Genetics

CBD-type genetics refer to cannabis cultivars selectively bred to express elevated cannabidiol (CBD) levels relative to tetrahydrocannabinol (THC). Modern CBD-dominant strains typically trace lineage to either high-CBD phenotypes discovered in heritage landraces or to deliberate crossing programs developed in the late 2000s–2010s. Breeders working in this category often employ marker-assisted selection and test-cross methodologies to stabilize CBD expression across generations. CBD-type cultivars commonly display biochemical profiles with CBD:THC ratios ranging from roughly 1:1 to 20:1 or higher, depending on strain and growing conditions. These genetics represent a distinct breeding focus within cannabis horticulture, separate from high-THC or balanced hybrid approaches.

Breeders use CBD-type genetics as parental stock to develop stable, consistent cultivars for research, commercial cultivation, and fiber/seed production programs. Understanding the genetic architecture of CBD synthase and related enzymes informs crossing strategies to maintain or enhance cannabinoid ratios across multiple generations.
