Myrcene Forward Chemotypes

Myrcene-forward chemotypes are cannabis plants in which myrcene comprises a notably elevated proportion of the total terpene profile, often exceeding 50% of detectable terpenes. Myrcene is the most abundant terpene across many cannabis varieties and is also found in hops, mango, and lemongrass. Plants classified as myrcene-forward typically exhibit earthy, herbal, or fruity aromatic notes, with breeding records frequently reporting associations with older landrace and hash plant lineages. Modern cultivars tagged with this chemotype often trace ancestry to Afghan, Moroccan, or Indica-dominant germplasm. Understanding myrcene-forward profiles is relevant for breeders seeking to preserve traditional chemotype characteristics or develop stable terpene phenotypes for specific market segments.

Breeders working with myrcene-forward chemotypes often select for plants expressing consistent, high myrcene production across generations. This classification helps identify parent material suitable for breeding programs focused on heritage phenotype preservation or terpene stability in F1 and inbred lines.
