Citrus Profiles

Citrus profiles refer to terpene combinations dominated by limonene and related compounds that produce lemon, orange, grapefruit, and tangerine-like aromas. These profiles arise from specific terpene synthase expression patterns during flower development and are influenced by both genetics and cultivation conditions. Citrus-dominant strains are commonly associated with Sativa-leaning lineages, particularly those descended from Haze, Citral, and Thai cannabis varieties. The volatile compounds responsible—including limonene, pinene, and myrcene in varying ratios—evaporate readily, making preservation and storage significant considerations for breeders working to maintain these aromatic phenotypes.

Breeders selecting for citrus profiles typically phenotype-hunt for limonene expression during flowering, as this trait shows moderate heritability across generations. Stabilizing citrus aromatics in F2 and F3 lines requires careful selection, since terpene ratios can shift significantly based on environmental factors like temperature and light spectrum during late bloom.
