Cbd Dominant Type I

CBD-dominant Type I cannabis refers to plants bred to produce higher concentrations of cannabidiol (CBD) relative to THC, typically with a CBD:THC ratio favoring CBD. This classification emerged in the early 2000s as breeders deliberately selected for high-CBD phenotypes, often using landrace varieties or backcrossing with CBD-rich genetics. Type I specifically denotes plants with meaningful CBD content alongside some THC presence, distinguishing them from Type III (CBD-only) and Type II (balanced CBD/THC) chemotypes. Lineage records frequently report Swiss, Italian, and Eastern European origins in modern CBD-dominant breeding programs. This category has become significant in breeding research exploring cannabinoid expression and phytochemical diversity.

Breeders working with CBD-dominant Type I genetics focus on stabilizing high-CBD expression while maintaining viable plant vigor and seed production. Selection programs often employ marker-assisted breeding or progeny testing to identify consistent CBD phenotypes across generations.
