Myrcene Dominant Phenos

Myrcene-dominant phenotypes represent cannabis lines where myrcene comprises a significant portion of the terpene profile, often exceeding 50% of total monoterpenes. This sesquiterpene is commonly associated with earthy, herbal, and sometimes fruity aromatic qualities. Myrcene-dominant phenos frequently appear in classic indica and indica-leaning hybrid lineages, though expression varies considerably across genotypes and environmental conditions. Breeders working in this category often observe correlations between high myrcene content and certain growth patterns, including shorter flowering windows and denser flower structures. The prevalence of myrcene-dominant phenotypes in established cultivar families suggests strong genetic stability for this trait across generations.

Breeders select for myrcene-dominant phenotypes to establish consistent aromatic signatures and to explore potential correlations with plant morphology and cannabinoid ratios. High myrcene lines serve as foundational genetics for hybridization programs seeking to introduce or emphasize this terpene profile into new crosses.
