Terpene Selection

Terpene selection refers to the intentional breeding practice of isolating and perpetuating specific volatile organic compound profiles across cannabis generations. Breeders analyze terpene expression—particularly dominant compounds like myrcene, limonene, pinene, and caryophyllene—to stabilize desired aromatic signatures within cultivars. This practice involves phenotype hunting, controlled crossing, and multi-generation stabilization to lock in terpene ratios that breed true. Terpene selection impacts both the sensory profile of a cultivar and potentially influences cannabinoid expression patterns through genetic linkage. Understanding terpene inheritance patterns helps breeders predict offspring aroma and develop consistent, reproducible strains.

Terpene selection is foundational to modern cultivar development. Breeders use gas chromatography (GC) and other analytical methods to screen parent plants and offspring, selecting for consistent terpene production across multiple grows and environmental conditions to achieve stable, branded chemotypes.
