Pinene Myrcene Profile

The Pinene-Myrcene profile describes cannabis lineages where these two terpenes occur as co-dominant or near-co-dominant compounds in the essential oil. Pinene, a bicyclic monoterpene, and myrcene, an acyclic monoterpene, frequently appear together in certain cultivar families—particularly those descended from Haze, Skunk, and Afghan landrace crosses. Lineage records suggest this terpene pairing emerged through selective breeding in the 1970s–1980s when breeders combined high-resin Indica-type plants with aromatic Sativa-dominant genetics. The profile is valued in breeding programs for its chemical stability and predictable expression across generations. Plants exhibiting this profile often display herbaceous, earthy, and woody aromatic notes with subtle fruity undertones.

Breeders working in this terpene class use pinene-myrcene dominance as a marker for vigor and resin production consistency. The pairing is common in backcross programs aiming to preserve parent-line aromatics while introducing new cannabinoid or morphology traits.
