Myrcene Limonene Ratios

Myrcene and limonene are two of the most prevalent monoterpenes in cannabis, and their relative proportions shape both the plant's aromatic profile and breeding objectives. Myrcene-dominant profiles (>0.5% by weight) are commonly associated with earthy, herbal, or clove-like aromas, while limonene-dominant strains often present citrus or fruity notes. Breeders tracking these ratios use gas chromatography and headspace analysis to identify and stabilize chemotypes across generations. Understanding myrcene-to-limonene balance is particularly relevant for cultivators selecting parent plants, as terpene ratios can remain relatively stable across clonal lines and seed-grown offspring when environmental conditions are controlled.

Myrcene-limonene ratios are a quantifiable target for selective breeding programs aiming to develop consistent aromatic profiles and predictable plant expression. Growers and breeders often use terpene ratio data to sort phenotypes, identify keeper plants, and document lineage characteristics across multiple generations.
