Dominant Terpene Profile

A dominant terpene profile refers to the most abundant volatile compounds present in a cannabis plant's chemical composition, typically determined through chromatographic analysis. In breeding records, strains are often categorized by their leading terpenes—such as myrcene, limonene, or caryophyllene—which frequently correlate with observable aroma characteristics. Understanding dominant terpene profiles helps breeders track chemical consistency across generations and identify lineage markers. Different cultivars within the same family may express varying dominant terpenes depending on environmental conditions, harvest timing, and genetic expression. This classification system supports objective strain documentation and genetic preservation efforts in cannabis research.

Breeders monitor dominant terpene profiles to maintain chemical stability in breeding lines and to select parent plants with desired aromatic traits. Tracking these profiles across generations helps establish which genes reliably produce consistent terpene expressions, informing decisions about crosses and strain stabilization.
