Myrcene Rich Genetics

Myrcene-rich genetics refer to cannabis lineages that consistently express elevated levels of myrcene, a sesquiterpene commonly associated with herbal and earthy aromatic profiles. These genetics are frequently selected by breeders working to establish stable terpene expression across generations. Lineage records often show myrcene dominance in strains descended from landrace or indica-leaning cultivars, though the trait can appear across diverse genetic backgrounds. Myrcene concentration is influenced by both genotype and cultivation conditions, making phenotype selection an important breeding tool. Understanding myrcene-dominant genetics helps breeders predict aromatic outcomes and maintain consistency in breeding programs.

Breeders often target myrcene-rich parents when developing cultivars for terpene stability or to establish baseline aromatic signatures within new crosses. Phenotypic selection and controlled pollination of high-myrcene individuals has allowed breeders to establish reliable myrcene expression in commercial lines.
