Limonene Citrus Terpene

Limonene is a monocyclic monoterpene commonly found in cannabis varieties alongside other citrus-associated terpenes like pinene and myrcene. This terpene family is frequently documented in strains descended from Lemon Haze, Citral, and other citrus-forward breeding lines. Limonene biosynthesis is influenced by genetic background, growing conditions, and harvest timing, making it a variable trait across phenotypes. Breeders working in this category often select parent plants demonstrating elevated limonene expression to stabilize citrus aromatics in F1 and F2 generations. The compound is also present in lemon peels, juniper, and other plants, and is widely studied in cannabis pharmacology literature.

Limonene-rich phenotypes are selected by breeders targeting citrus flavor profiles and as a marker trait for specific genetic lineages. Understanding limonene stability across generations helps breeders develop consistent seed lines and identify which crosses reliably produce this terpene expression.
