Citral Terpene Group

Citral is a naturally occurring acyclic monoterpene commonly found in cannabis cultivars, particularly those with Lemon Haze and Citrus-forward lineages. The compound exists as two geometric isomers—geranial and neral—which together create the bright, lemony-fresh aromatic profile breeders often seek in modern cultivars. Citral-dominant strains are frequently reported in sativas and hybrid breeding lines, especially those descended from Thai and Central Asian cannabis genetics. This terpene is structurally related to other monoterpenes like limonene and myrcene, though it presents a distinct sensory signature. Understanding citral's presence in breeding stock helps geneticists track aromatic expression across generations and select for specific terpene profiles in commercial programs.

Breeders working with citral-rich cultivars often use them as aromatic donors in crossing programs to establish or enhance bright, clean citrus notes in new lines. Selection for citral prominence typically correlates with specific phenotypic markers and growing conditions, making it a useful trait marker for stabilizing desired aroma profiles in F2 and backcross generations.
