Limonene

Limonene is a monoterpene commonly found across cannabis genetics, particularly in sativa-leaning and hybrid lineages. This volatile compound is frequently associated with citrus aromatics—lemon, lime, and grapefruit notes—though its presence and expression vary significantly across cultivars and phenotypes. Limonene is not unique to cannabis; it occurs widely in nature, especially in citrus peels and other plants. In cannabis breeding records, limonene-forward chemotypes are often selected from parent plants showing bright, sharp aromatic profiles. Genetic expression of limonene levels is polygenic and influenced by both cultivar lineage and environmental factors during cultivation.

Breeders working in sativa and hybrid categories frequently prioritize limonene-rich parent selection to develop aromatic profiles valued in commercial markets. Phenotypic screening for limonene expression is a standard practice in lineage development, though terpene ratios remain difficult to predict across generations without direct testing.
