Farnesol

Farnesol is a sesquiterpene alcohol found in cannabis and numerous botanical sources including citrus peels and rose oil. This compound appears in trace to minor concentrations in most cannabis varieties, though certain cultivars bred for specific terpene profiles may express it more prominently. Farnesol is characterized by a floral, slightly woody aroma with subtle citrus undertones. In cannabis breeding, farnesol often co-occurs with other sesquiterpenes and can contribute to the overall aromatic complexity of a cultivar's terpene profile. Its presence is commonly associated with cultivars descended from heritage landrace genetics or those deliberately selected for floral-forward aromatics.

Breeders tracking farnesol typically focus on phenotype selection and terpene profiling when establishing lines valued for aromatic complexity. Cultivars expressing elevated farnesol are often incorporated into breeding programs aimed at developing cultivars with distinctive floral or woody character profiles.
