Geraniol Suppression

Geraniol suppression refers to breeding lineages or cultivars that show notably reduced levels of geraniol—a common monoterpene often associated with floral, rose-like, or citrus aromatics. While geraniol frequently appears across cannabis chemotypes, some breeders have worked to minimize or eliminate it through selective crosses, often resulting in altered terpene profiles where other compounds become more prominent. This trait is less commonly isolated as a discrete family compared to terpene-dominant strains, but lineage records occasionally document suppressed geraniol as a secondary characteristic when breeders prioritize other volatile compounds. Understanding geraniol suppression helps contextualize how terpene engineering and phenotypic selection shape the sensory complexity of modern cultivars.

Breeders working toward specific flavor targets—particularly those aiming for piney, herbal, or fuel-forward profiles—may select for geraniol suppression to reduce floral notes and allow myrcene, pinene, or other terpenes to dominate. This trait demonstrates how selective breeding can push terpene balancing rather than simply amplifying single compounds.
