Terpene Marker System

The Terpene Marker System is a classification framework used by cannabis breeders and researchers to identify and track secondary volatile compounds that define aromatic profiles and phenotypic expression. Rather than focusing on cannabinoid content, this system catalogs the presence and relative abundance of specific terpenes—such as myrcene, limonene, pinene, and caryophyllene—as genetic markers for selective breeding. Terpene profiles are commonly associated with strain family identity and environmental adaptation, making them valuable tools for phenotype selection and cultivar development. The system helps distinguish between closely related genetics and supports reproducible breeding programs by standardizing how aromatic traits are documented and transmitted across generations.

Breeders use terpene marker systems to accelerate phenotype stabilization, identify desirable aromatic lineages, and maintain cultivar consistency across seed runs. Tracking specific terpene combinations allows structured selection for market-defined aroma classes without relying solely on visual or potency traits.
