Single Terpene Chemotypes

Single terpene chemotypes are cannabis lines where one terpene compound dominates the volatile profile, often comprising 40–70% or more of total terpene content. These strains result from selective breeding focusing on genetic expression of specific monoterpenes (like limonene, myrcene, or pinene) or sesquiterpenes (like caryophyllene). Lineage records frequently report single-terpene dominance emerging through repeated backcrossing to parents displaying pronounced aromatic profiles. Understanding these chemotypes is valuable for genetic mapping, as they reveal terpene-linked traits that may correlate with cannabinoid ratios or plant structure. Single terpene lines serve as breeding tools for creating hybrid profiles or studying terpene biosynthesis pathways.

Breeders working with single terpene chemotypes use them as genetic reference points to isolate and amplify specific aromatic traits. These lines are often crossed with morphologically distinct strains to combine terpene clarity with desired plant structure, yield characteristics, or cannabinoid profiles.
