Phytochemical Classification

Phytochemical classification organizes cannabis compounds into chemical families—cannabinoids, terpenes, flavonoids, and phenolic compounds—based on their molecular structure and biosynthetic pathways. Rather than describing subjective sensory experience, this framework provides breeders and researchers with a precise vocabulary for tracking inherited chemical traits across generations. Understanding phytochemical groupings helps distinguish between plants with similar aromas but different underlying chemistry, and between genetically distinct lineages that may produce superficially similar terpene profiles. This classification system is foundational to modern cannabis genetics work, enabling more predictable crosses and clearer documentation of chemotype stability.

Breeders use phytochemical classification to map heritable traits with greater precision than phenotype alone, identifying which genetic lines consistently produce specific monoterpene or sesquiterpene ratios. This approach facilitates targeted crosses aimed at stabilizing desired compound profiles across multiple generations.
