Sesquiterpene Dominance

Sesquiterpene dominance refers to cannabis chemotypes where C15 sesquiterpenes comprise a substantial portion of the volatile profile, often exceeding monoterpene (C10) concentrations. Common sesquiterpenes in cannabis include β-caryophyllene, β-myrcene, and humulene, which are frequently associated with earthy, woody, and spicy aromatic notes. This profile tends to emerge in older, landrace, and indica-leaning lineages, though modern breeding has produced diverse chemotypes across morphotypes. Sesquiterpene-dominant cultivars often exhibit slower volatile development during early curing compared to monoterpene-forward varieties. Understanding sesquiterpene dominance is essential for breeders selecting for specific aroma profiles and for seed producers preserving lineage authenticity.

Breeders working in this category often prioritize parent selection from proven sesquiterpene-forward lines to stabilize earthy and woody character across generations. This trait is particularly valued in preservation breeding and in developing cultivars marketed toward specific regional or traditional aroma expectations.
