Terpene Profile Mapping

Terpene profile mapping is the analytical process of identifying and quantifying volatile compounds present in cannabis plant material. This technique documents the specific terpenes, their relative concentrations, and their chemical ratios across different plant tissues, growth stages, or cultivars. Breeders and researchers use chromatography methods—such as gas chromatography (GC) or liquid chromatography (LC)—to generate reproducible terpene fingerprints. Profile mapping serves as a foundation for understanding strain consistency, lineage markers, and how cultivation variables influence secondary metabolite expression. This data supports breeding decisions and helps distinguish genetic backgrounds within closely related cultivars.

Breeders use terpene profile mapping to identify parent plants with desired aromatic signatures, track trait expression across generations, and select for stable terpene production. Consistent mapping protocols enable breeders to verify genetic purity and document how specific crosses influence volatile compound inheritance.
