Cbd Dominance

CBD dominance refers to cannabis plants bred to express cannabidiol (CBD) at levels notably higher than tetrahydrocannabinol (THC), typically in ratios of 20:1 or greater. This classification emerged from selective breeding efforts beginning in the early 2010s, driven by interest in non-intoxicating cannabis genetics. CBD-dominant strains are often created by crossing high-CBD cultivars with low-THC parents or through targeted selection within hemp-derived lineages. Breeders working in this category frequently document cannabinoid profiles through third-party testing to establish consistency. The trait represents a significant departure from historical cannabis breeding priorities and reflects expanding applications in agricultural and research contexts.

Breeders develop CBD-dominant lines through multi-generational selection, backcrossing, and sometimes hybridization with high-CBD hemp genetics. Stability of the CBD:THC ratio across phenotypes is a key breeding objective, requiring consistent testing and careful parent selection to minimize THC expression.
