Myrcene Limonene Reduction

Myrcene Limonene Reduction refers to a family of cannabis lines selected for notably low levels of both myrcene and limonene terpenes relative to their parent populations. Breeders pursuing this phenotype typically target plants where these two abundant terpenes are suppressed in favor of other volatile compounds—creating chemotypes with distinct aromatic and chemical profiles. This reduction is often achieved through selective breeding across multiple generations, identifying and stabilizing individuals that naturally express lower terpene concentrations in these categories. Lineage records frequently report such material emerging from diverse genetic backgrounds, suggesting the trait may be controlled by multiple loci. The family has relevance primarily in research breeding contexts and among cultivators seeking chemotype diversity beyond myrcene- or limonene-dominant profiles.

Breeders working in this category use myrcene-limonene reduction lines as foundation stock to explore alternative terpene expression—particularly to amplify minor terpenes like pinene, caryophyllene, or humulene. Stabilizing these phenotypes requires multi-generational selection and chemotype verification via gas chromatography or similar analytical methods.
