Myrcene Reduction

Myrcene Reduction refers to cannabis breeding lines selected for lower myrcene terpene expression relative to typical cultivars. Myrcene is the most abundant terpene in most cannabis strains, commonly contributing earthy and herbal aromatic notes. Breeders working in this category have isolated genetic markers and selection protocols that suppress myrcene biosynthesis while maintaining other terpene profiles. This family includes stabilized lines where myrcene comprises a smaller percentage of the overall terpene envelope. Documentation of myrcene reduction often appears in third-party lab reports and breeder lineage records, though expression can vary by environment and phenotype. Understanding myrcene-reduced genetics is relevant for cultivators seeking diverse terpene diversity in breeding programs.

Myrcene reduction is used in crossing programs to create cultivars with more pronounced secondary terpenes—such as limonene, pinene, or caryophyllene—without typical myrcene dominance. Breeders employ this trait to expand the aromatic palette available in commercial and private collections.
