Myrcene Dominant Families

Myrcene-dominant families represent cannabis strains where myrcene constitutes the primary terpene profile, often comprising 40–60% of total terpene content. Lineage records frequently report myrcene prominence in wide-leafed indica types and many landrace accessions, particularly those derived from Afghan, Pakistani, and Southeast Asian breeding stock. The terpene's prevalence in these families is often attributed to selection pressure for specific plant phenotypes—compact structure, resin density, and flowering time—rather than direct terpene targeting by early breeders. Modern cultivars in this category include well-documented crosses built on high-myrcene parent genetics. Understanding myrcene-dominant families helps breeders evaluate terpene inheritance patterns and predict chemotype stability across generations.

Breeders working in myrcene-dominant families use these strains as terpene-stable parent material for crosses aimed at maintaining consistent aromatic profiles or exploring how myrcene interacts with secondary terpenes like caryophyllene and pinene. High-myrcene genetics serve as reliable baseline material for chemotype documentation and cannabinoid-to-terpene ratio studies.
