Volatile Compound Mapping

Volatile compound mapping refers to the analytical process of identifying and quantifying the aromatic compounds released by cannabis plant material. This technique typically employs gas chromatography (GC) or gas chromatography-mass spectrometry (GC-MS) to detect terpenes, esters, aldehydes, and other volatile organic compounds that contribute to a strain's distinctive scent profile. Breeders and researchers use mapping data to document the chemical signatures associated with specific lineages and phenotypes. Accurate volatile mapping helps establish baseline chemical profiles that can be tracked across generations, supporting selection work focused on particular aroma characteristics. This methodology is foundational to understanding how genetic inheritance influences the sensory compounds expressed in different cultivars.

Breeders working in selective aroma development use volatile compound mapping to track which parental genetics reliably produce desired volatile profiles. By correlating mapped compounds with phenotypic observations across multiple generations, breeders can make informed crosses and stabilize specific aroma signatures in new lines.
