Sesquiterpene Family

Sesquiterpenes are a large class of volatile compounds comprising 15 carbon atoms, commonly found across cannabis cultivars and many plant species. Within cannabis genetics, sesquiterpenes like β-caryophyllene, β-myrcene, humulene, and α-bisabolol are frequently documented in terpene profiles and lineage records. These compounds are often tagged as contributors to the aromatic complexity of cannabis flowers, alongside their role in plant defense and volatile expression during growth. Breeders studying sesquiterpene-dominant chemotypes have noted consistent inheritance patterns across certain strain families, particularly those with Haze, Skunk, and indica-dominant ancestry. Sesquiterpene content and ratios are considered important selection markers in contemporary breeding programs focused on terpene stability.

Breeders working in sesquiterpene expression commonly select parent plants with stable sesquiterpene-rich profiles to establish predictable terpene ratios in offspring. Understanding sesquiterpene genetics enables targeted crosses aimed at specific aroma and volatile compound goals, supporting both preservation and innovation in established strain families.
