Citral Terpene Expression

Citral is a C10 monoterpene comprising geranial and neral isomers, commonly identified in cannabis through gas chromatography analysis. Strains expressing elevated citral levels are often tagged as possessing lemon, lime, or grapefruit aromatic notes. This terpene is frequently associated with Sativa-leaning genetics and certain Haze lineages, though citral expression varies significantly by cultivar, growing conditions, and harvest timing. Citral's presence in the terpene profile is documented across diverse breeding programs, particularly those targeting bright, zesty aroma characteristics. Understanding citral expression helps breeders evaluate phenotypic stability and aroma consistency across seed generations.

Breeders working in this category often select parent plants exhibiting consistent citral-dominant profiles to establish stable aroma traits in offspring. Citral expression serves as a useful phenotypic marker during pheno-hunting, as gas chromatography or headspace analysis can quantify this monoterpene's contribution to overall volatile profiles.
