Geranial And Neral

Geranial and neral are geometric isomers—compounds with identical molecular formulas but different spatial structures—commonly found together in cannabis terpene profiles. Geranial (also called citral a) and neral (citral b) are acyclic monoterpenes frequently associated with citrus and floral aromatics in certain cultivars. These isomers often appear as part of the broader citral compound class and are tracked by analytical labs using chromatography methods. Lineage records frequently report elevated geranial and neral in strains descended from Lemon or Haze-family genetics. Breeders working to enhance bright, fresh terpene profiles may select for parent plants expressing higher ratios of these isomers, though environmental conditions during cultivation significantly influence final terpene ratios.

Breeders monitor geranial-to-neral ratios as a genetic marker for consistency in aromatic phenotypes. Selection for these isomers is often paired with breeding for other citrus-associated terpenes like limonene and myrcene to establish stable terpene profiles across generations.
