Camphene Expression

Camphene is a bicyclic monoterpene often detected in cannabis cultivars, particularly in lineages with heritage connections to landrace or OG-type genetics. This volatile compound is characterized by a sharp, camphor-forward aroma frequently accompanied by herbal and woody undertones. Camphene typically appears in lower concentrations than dominant terpenes like limonene or myrcene, yet breeders working in certain chemotype categories intentionally preserve or select for its expression. Presence of camphene is commonly associated with specific terpene profiles rather than being a dominant aromatic marker. The compound's stability and expression patterns are of interest to breeding programs focused on aroma complexity and terpene profile differentiation.

Breeders track camphene expression as a minor-terpene marker to maintain chemotype consistency across generations and to develop cultivars with nuanced aromatic profiles. Selection for camphene-rich phenotypes is often combined with other monoterpene targets to create distinctive terpene signatures in commercial and research lines.
