Sesquiterpene Reduction Breeding

Sesquiterpene reduction breeding focuses on cannabis lines selected for lower concentrations of heavier terpenes (C15 compounds like caryophyllene, humulene, and β-myrcene). Breeders pursuing this strategy often target aromatic profiles dominated by lighter monoterpenes, or aim to shift the sesquiterpene ratio to emphasize specific compounds over others. This approach has been documented in both hemp and cannabis breeding programs working toward particular sensory or chemical profiles. Sesquiterpene-reduced lines may display different volatility and storage characteristics compared to sesquiterpene-dominant genetics. The breeding work typically involves multi-generation selection and GC-MS analysis to monitor terpene shifts across populations.

Breeders use sesquiterpene reduction to stabilize aromatic consistency, improve shelf-life through reduced degradation of volatile compounds, and create distinct chemotype populations for research or targeted cultivation. This trait is particularly relevant in preservation-focused breeding and in programs developing strains with altered sensory profiles.
