Myrcene Dominant Genetics

Myrcene-dominant genetics refer to cannabis cultivars where myrcene comprises the largest proportion of the terpene profile. Myrcene is a monoterpene commonly found across cannabis, hops, and various plants, often contributing to earthy and herbal aromatics. Lineage records frequently report myrcene dominance in many landrace and modern hybrid populations, particularly those descended from Indica-leaning or Southeast Asian ancestry. Breeders and researchers identify myrcene presence through gas chromatography and headspace analysis, making it a measurable marker in strain development. Understanding myrcene-dominant families is valuable for cultivators studying terpene expression and for breeding programs focused on specific aromatic profiles.

Breeders working with myrcene-dominant genetics often select for this trait when developing lines intended for particular sensory characteristics or when stabilizing heritage cultivars. Myrcene expression is influenced by growing conditions, harvest timing, and genetic background, making it a useful phenotype marker during parent selection and hybrid evaluation.
