Terpenome Mapping

Terpenome mapping refers to the systematic cataloging and analysis of terpene profiles within cannabis germplasm. This approach involves identifying, measuring, and documenting the specific volatile compounds produced by different strains and cultivars. Terpenome mapping has become increasingly important in cannabis breeding research, allowing geneticists to correlate terpene expression with plant lineage, growth conditions, and chemotype stability. The practice bridges modern analytical chemistry (gas chromatography, mass spectrometry) with classical breeding records to build searchable databases of terpene inheritance patterns. This work is foundational for breeders seeking to stabilize desirable aromatic or flavor traits across generations.

Breeders use terpenome mapping data to predict aromatic outcomes when crossing parent lines, identify which strains consistently express rare terpene combinations, and select for chemotype stability in inbred or F1 hybrid programs. Mapping studies also help identify genetic markers linked to terpene biosynthesis pathways, accelerating trait selection in early-generation material.
