Myrcene Based Terpene Families

Myrcene-based terpene families represent a large cluster of cannabis chemotypes where myrcene—a C10H16 monoterpene—comprises a significant proportion of the volatile profile, often ranging from 20–65% of total terpenes. Lineage records frequently report myrcene dominance in indica-spectrum plants, particularly those descended from Afghan and Southeast Asian landrace genetics. These chemotypes are commonly associated with earthiness, herbal, and sometimes fruity or clove-like aromatic notes. Myrcene's boiling point (166°C) and volatility mean preservation of these profiles requires careful drying and storage. Understanding myrcene-rich families helps breeders categorize phenotypic stability and predict aromatic consistency across generations.

Breeders working in this category often use myrcene-dominant parents as genetic anchors for consistency in aroma and terpene reproducibility. High-myrcene lines are valuable for crossing programs aiming to establish herbal or spice-forward flavor profiles in hybrid development.
