Myrcene Rich Genetics

Myrcene-rich genetics refer to cannabis cultivars that consistently express elevated levels of β-myrcene, a sesquiterpene commonly associated with earthy, herbal, and fruity aromatic profiles. Lineage records frequently report myrcene dominance in OG Kush, Skunk, and Indica-leaning families, where the compound often comprises 20–65% of total terpene profiles. Breeders have long selected for myrcene prominence due to its stability across growing conditions and its role in cannabis's characteristic pungency. Understanding myrcene genetics is valuable for cultivators seeking predictable aroma and for researchers studying terpene biosynthesis pathways in the species.

Commercial and craft breeders often target myrcene-rich parent stock when developing stable, aromatic lines intended for extract or dried flower markets. Myrcene's boiling point (~167°C) and relative volatility make it a marker trait for assessing harvest timing and post-harvest preservation protocols.
