Citral Compound Expression

Citral compound expression refers to the relative abundance of citral isomers (geranial and neral) in cannabis terpene profiles. These C10 monoterpenes are commonly associated with lemon, lime, and citrus-forward aromas and frequently appear across diverse cultivars and lineages. Citral expression varies significantly between individual plants within the same strain, influenced by genetic background, cultivation conditions, and harvest timing. Lineage records frequently report citral-dominant profiles in certain regional landrace types and modern breeding lines derived from Lemon Haze, Super Lemon Haze, and related citrus-leaning parent stocks. This classification is particularly relevant for breeders seeking consistent aroma markers and for understanding terpene consistency across generations.

Breeders working in this category select for citral stability across generations to establish predictable sensory profiles and explore potential synergies with other terpene classes. Citral expression is often used as a phenotype marker in hybrid development, as it remains relatively heritable under controlled conditions.
