Terpenes

Terpenes are volatile organic compounds produced by cannabis plants that contribute to aroma, flavor, and plant biology. These molecules are found across the plant kingdom and serve various ecological functions, from attracting pollinators to protecting against pathogens. In cannabis genetics, terpene profiles are heritable traits influenced by both genotype and environmental conditions during cultivation. Breeders track terpene composition as a secondary marker of strain identity alongside cannabinoid ratios. Understanding terpene families—including monoterpenes, sesquiterpenes, and diterpenes—helps geneticists classify lineages and predict aromatic characteristics across generations. Terpene research in cannabis breeding remains largely observational rather than mechanistically understood at the molecular level.

Breeders select parent plants partly based on terpene profiles to establish consistent aromatic signatures in cultivars. Terpene expression serves as a phenotypic indicator of genetic stability and can influence consumer-facing product differentiation, though environmental factors significantly alter final composition.
