Myrcene Co Expression

Myrcene co-expression refers to the simultaneous presence of myrcene alongside other dominant terpenes in a cannabis phenotype, rather than myrcene acting as the sole primary aromatic compound. This terpene interaction often occurs in strains where myrcene comprises 20-50% of the total terpene profile, frequently accompanied by limonene, caryophyllene, or pinene. Lineage records suggest co-expression patterns are heritable traits influenced by parent genetics and environmental conditions during cultivation. Understanding these multi-terpene profiles is valuable for breeders seeking to develop distinct aromatic signatures and for researchers studying how terpene combinations arise in cannabis varieties.

Breeders working with myrcene co-expression focus on stabilizing complementary terpene ratios across generations, as these combinations can distinguish cultivars in competitive markets. Selecting parent plants with consistent secondary terpene expression alongside myrcene helps create reproducible flavor and aroma profiles.
