Myrcene Dominant Families

Myrcene-dominant families represent cannabis lineages where myrcene comprises a substantial portion of the volatile terpene profile, often 20-65% of total terpenes. These families are frequently encountered across indica-type cultivars and many hybrid lines, with myrcene commonly associated with herbaceous, earthy, and clove-like aromatic notes. Breeders working in this category have historically selected parent plants exhibiting elevated myrcene production, leading to stabilized phenotypes across multiple generations. Myrcene's prevalence in certain families reflects both genetic predisposition and environmental expression patterns, making lineage selection a primary breeding tool. Documentation of myrcene levels varies across seed banks and labs, though GC-MS analysis remains the standard for quantification.

Breeders pursuing myrcene-dominant traits typically cross established high-myrcene parents or backcross to myrcene-expressive individuals to concentrate the terpene. This approach is foundational in developing cultivars marketed within specific sensory categories, though actual myrcene percentages require third-party verification.
