Low Cbd Expression
Low CBD expression refers to cannabis plants that produce minimal cannabidiol (CBD) relative to other cannabinoids, typically under 1% CBD by dry weight. This phenotype has become standard in many modern cultivars, particularly those developed during decades of THC-dominant breeding. CBD and THC production are influenced by the CBDAS and THCAS enzyme genes; low CBD strains commonly express variants that favor THC synthesis pathways. Understanding CBD expression levels is important for breeders working with specific cannabinoid ratios, as many contemporary genetics were selected for THC prominence rather than balanced cannabinoid profiles. Lineage records frequently show that low CBD became a dominant trait in Western breeding programs from the 1970s onward.

Breeders use low CBD parent plants when creating THC-dominant lines or when seeking to maintain specific cannabinoid profiles in hybrid crosses. Conversely, breeders seeking balanced or CBD-forward genetics often avoid low CBD parents, instead selecting from rare cultivars or heirloom strains with higher CBD expression.
