Monoterpene Dominant Phenotypes

Monoterpene-dominant phenotypes are cannabis cultivars in which single terpenes constitute a notably higher proportion of the volatile profile than in polyphonic chemotypes. These expressions frequently occur in established lineages like Limonene-dominant Sour Diesel or Myrcene-dominant OG varieties, where selective breeding has stabilized elevated levels of one aromatic compound. Breeders document monoterpene dominance through gas chromatography analysis, which distinguishes these chemotypes from more complex, multi-terpene profiles. This classification is relevant to seed development and preservation work, as monoterpene-stable genetics offer reproducible aromatic consistency across generations. Understanding monoterpene dominance helps cultivators and breeders predict aromatic stability and potential phenotypic variation within a line.

Breeders working toward monoterpene-dominant expressions often select parents showing elevated single-terpene production, then stabilize those traits through multiple generations of selection. Monoterpene-dominant lines serve as genetic anchors for backcrossing programs and for creating predictable, consistent seed offerings.
