D Limonene

D-limonene is a terpene classified as a monocyclic monoterpene commonly found in cannabis cultivars alongside other citrus-associated compounds. In cannabis genetics, strains tagged with d-limonene aromas often derive lineage from cultivars selected for citrus or lemon-forward terpene profiles. Breeders working in this category frequently report d-limonene presence in sativa-leaning hybrids and specific Haze, Lemon, and Citrus chemotypes. The compound is one of the most abundant terpenes across plant biology, making it a stable trait for selective breeding programs. D-limonene-forward strains typically present recognizable bright, lemony, or grapefruit-like aromatic notes that emerge during curing and combustion.

Breeders select for d-limonene expression to stabilize citrus aromatic profiles and to work with established chemotype lines like Lemon Haze crosses. D-limonene abundance is often correlated with sativa-dominant or hybrid structure in breeding records, making it a useful marker for phenotype selection.
