Sesquiterpene Genetics

Sesquiterpenes are a large class of volatile organic compounds found across cannabis genetics, characterized by 15-carbon backbones and diverse structural forms. Common sesquiterpenes in cannabis include β-caryophyllene, β-myrcene, humulene, and α-bisabolol, each contributing distinct aromatic signatures and potential breeding targets. These compounds are often tagged as secondary metabolites that develop during flower maturation and are frequently studied in terpene profiling work. Sesquiterpene expression varies significantly across strain lineages, with some cultivars showing dominant sesquiterpene profiles while others produce only trace amounts. Breeders working in this category track sesquiterpene ratios as one marker among many for phenotype selection and stability testing.

Sesquiterpene genetics are valuable to breeders developing stable aromatic profiles and studying heritability of secondary metabolites. Cultivation practices and environmental stress can shift sesquiterpene expression, making consistent genetics documentation important for reproducible breeding programs.
