Sesquiterpene Expressions

Sesquiterpene expressions refer to aromatic profiles dominated by C15 hydrocarbons—larger molecular structures than monoterpenes that contribute deeper, earthier, and more persistent scent characteristics. These compounds are commonly found in cannabis cultivars alongside monoterpenes and often create layered aromatic complexity. Breeders frequently report sesquiterpenes like caryophyllene, humulene, and β-myrcene as key markers in lineage development. Sesquiterpene-forward cultivars are often tagged as having woody, spicy, herbal, or musky notes. Understanding sesquiterpene expression helps breeders target specific aromatic breeding goals across generations. Preservation of sesquiterpene profiles during seed storage and cultivation requires attention to temperature and light exposure.

Breeders working in sesquiterpene-focused categories use selective crosses to stabilize these heavier compounds across offspring, as sesquiterpene ratios can shift with environmental factors and plant maturity. Sesquiterpene-dominant parents are often chosen to establish consistent aromatic phenotypes in hybrid lines.
