Citral Expression

Citral Expression refers to cannabis genetics selected for prominent citral terpene profiles, where limonene, myrcene, and geranial/neral compounds create characteristic lemon, lime, and grapefruit aromatics. Citral-dominant strains emerge from breeding programs targeting these volatile compounds, often traced through Sativa-leaning or hybrid lineages known for terpene complexity. Breeders document citral expression variability across environmental conditions, with temperature and humidity significantly influencing terpene ratios during flowering and curing. This family appears frequently in modern cultivar development due to consumer interest in bright aromatic profiles and the relative stability of citral chemistry across multiple generations.

Breeders working with citral expression select parent plants through chromatographic testing and sensory evaluation to maintain high limonene and myrcene retention. Citral-forward genetics serve as foundation stock for creating flavor-distinct hybrid lines while maintaining cannabinoid stability and plant vigor.
