Cbd Expression
CBD expression refers to a plant's genetic capacity to produce cannabidiol (CBD) as a primary cannabinoid, rather than THC-dominant profiles. This trait is controlled by multiple genetic loci, with the CBDA synthase enzyme catalyzing the conversion of cannabigerolic acid (CBGA) to CBDA—the acidic precursor to CBD. Plants displaying high CBD expression often carry recessive alleles that suppress or redirect THC biosynthesis pathways. CBD-dominant and CBD-rich cultivars have become increasingly important in breeding programs seeking to stabilize this expression across generations. Understanding CBD expression is essential for breeders working with hemp genetics, fiber strains, and balanced cannabinoid profiles.

Breeders select for CBD expression through controlled crosses of known CBD-producing parents and progeny testing to identify homozygous or stable heterozygous lines. Stabilizing CBD expression across multiple generations requires understanding epistatic interactions and environmental factors that can influence cannabinoid ratios in the final plant material.
