Terpene Reduction Selection

Terpene Reduction Selection refers to breeding practices where cultivators intentionally select for cannabis plants expressing lower volatile organic compound profiles. This approach involves identifying and propagating individuals that show diminished aromatic intensity across their cannabinoid-rich tissues. Breeders pursuing this trait typically use sensory evaluation and gas chromatography to measure terpene concentrations across generations. The motivation varies: some seek to isolate cannabinoid expression independent of aromatic compounds, others target specific end-use applications where minimal smell is desired during cultivation or processing. This selection method requires careful lineage tracking to maintain stability across multiple generations while suppressing terpene biosynthesis pathways.

Terpene reduction is primarily used in research breeding programs studying cannabinoid pharmacology in isolation, and in industrial hemp cultivation where low-odor phenotypes reduce regulatory and neighbor-relation concerns. Growers working with this trait document parental genetics and offspring ratios to identify whether reduction is heritable and controlled by single or polygenic factors.
