Myrcene Dominant Breeding

Myrcene-dominant breeding refers to cultivars selected or developed for elevated myrcene terpene expression. Myrcene is one of the most abundant terpenes in cannabis, commonly associated with herbal, earthy, and sometimes fruity aromatic profiles. Breeders working in this category often prioritize parent plants with consistent myrcene production across generations. This trait appears frequently in indica-leaning and hybrid lineages, though myrcene expression varies considerably based on environmental factors, harvest timing, and individual plant genetics. Understanding myrcene-dominant families helps breeders predict terpene stability and aroma consistency in offspring.

Breeders select for myrcene dominance to establish distinctive aromatic signatures and to maintain terpene profiles across multiple generations. High-myrcene parents are often crossed to stabilize this trait in F1 and F2 lines, making it a reliable marker for phenotype selection.
