Sesquiterpene Profiles

Sesquiterpenes are fifteen-carbon terpene compounds that appear in cannabis resin and contribute to the plant's aromatic and chemical diversity. Common sesquiterpenes in cannabis include caryophyllene, humulene, and beta-myrcene, each with distinct molecular structures and volatile properties. These compounds are studied by breeders and chemists for their role in the plant's overall terpene profile and their presence across different cultivar families. Sesquiterpene ratios vary significantly between strains and can shift during cultivation, curing, and storage. Understanding sesquiterpene profiles helps breeders document genetic expression and track consistency within seed lines. Classification of sesquiterpene dominance is part of broader cannabis phytochemistry mapping efforts.

Breeders working with sesquiterpene-dominant lines use selective crosses to maintain or shift terpene expression across generations. Sesquiterpene profiles serve as phenotypic markers for distinguishing cultivar families and tracking genetic stability in seed development programs.
