Phytochemistry Markers

Phytochemistry markers refer to the characteristic chemical compounds—primarily terpenes, flavonoids, and cannabinoids—that define a cannabis strain's aromatic and sensory profile. These molecular signatures are often used by breeders and researchers to classify and identify plant chemotypes, establishing consistency across generations. Markers include compounds like myrcene, limonene, pinene, and caryophyllene, which contribute to observable aroma patterns and are frequently tracked in breeding programs. Understanding phytochemistry markers helps distinguish strain families and predict cultivation traits, though actual compound profiles vary based on environment, harvest timing, and post-harvest handling. This knowledge supports selective breeding for stable, recognizable phenotypes rather than relying on marketing terminology alone.

Breeders use phytochemistry markers as objective selection criteria to stabilize desired aromatic and growth characteristics across generations. By testing for specific terpene and cannabinoid ratios, cultivators can identify and perpetuate parent plants that produce consistent offspring with predictable chemotypes.
