Cbd Suppression

CBD suppression refers to cannabis lineages where cannabidiol (CBD) production is genetically minimized or nearly absent, resulting in plants that express predominantly THC-dominant chemotypes. This trait arises from specific allelic combinations at loci governing cannabinoid synthesis pathways, particularly mutations or regulatory variants that redirect precursor molecules toward THC rather than CBD. Breeders working in high-THC categories have historically selected for CBD suppression to maximize THC yield and potency in commercial and research contexts. The trait is often observed in modern cultivars derived from Afghan, Thai, and Colombian landrace hybridization programs. Understanding CBD suppression is relevant for both heritage preservation—identifying which modern strains retain balanced cannabinoid ratios—and for specialized breeding objectives targeting specific cannabinoid pro

Breeders use CBD suppression as a selection criterion when developing THC-dominant lines for particular market segments and research applications. Conversely, understanding suppression mechanisms helps cultivators and seed companies identify and preserve CBD-rich or 1:1 THC:CBD genetics, which require different parent stock selection.
