Myrcene Dominant Cultivars

Myrcene-dominant cultivars are cannabis strains where myrcene represents the most abundant terpene in the plant's volatile profile, typically comprising 20-65% of total terpene content. Myrcene is a monoterpene also found in hops, mangoes, and bay leaves, contributing earthy, herbal, and sometimes fruity aromatic notes. Lineage records frequently report myrcene dominance in many landrace and modern indica-influenced varieties, though the trait can appear across diverse genetic backgrounds. Breeders often select for myrcene-dominant phenotypes when developing cultivars for specific aromatic profiles or when stabilizing particular chemotype expressions. Understanding myrcene distribution helps geneticists track how parent genetics influence offspring terpene ratios and predict sensory outcomes across generations.

Myrcene dominance is a heritable trait influenced by multiple genetic loci, making it useful for breeders targeting consistent aromatic signatures across seed lines. Selecting parent plants with stable, high myrcene expression can help establish true-breeding cultivars with predictable terpene profiles for commercial consistency.
