Myrcene Forward Genetics

Myrcene-forward genetics describe cannabis breeding lines selected for elevated myrcene terpene expression. Myrcene is the most abundant monoterpene in many cannabis cultivars and is commonly associated with earthy, herbal, and fruity aromatic profiles. These genetics are identified through terpene profiling and selective breeding rather than cannabinoid ratios. Breeders working in this category often cross parent plants with documented myrcene-dominant chemotypes to stabilize the trait across generations. This classification focuses on terpene expression patterns and olfactory characteristics rather than psychoactive or therapeutic properties.

Myrcene-forward lines serve as foundational genetics for creating cultivars with specific flavor and aroma profiles. Breeders leverage these parents to predictably introduce myrcene-dominant phenotypes into hybrid programs and establish consistent terpene signatures in commercial or preservation collections.
