Terpenoid Inheritance

Terpenoid inheritance refers to the genetic transmission of volatile aromatic compounds—terpenes and terpenoids—from parent cannabis plants to offspring. These compounds, including myrcene, limonene, pinene, and caryophyllene, are produced in trichome glands and shaped by both nuclear and potentially cytoplasmic genetic factors. Breeders track terpenoid profiles across generations to understand heritability patterns and stabilize desirable aromatic phenotypes. Terpenoid inheritance is often complex, influenced by multiple genes and environmental growing conditions, making it a critical focus in modern cannabis breeding programs seeking consistent aroma and flavor stability.

Breeders selectively cross plants exhibiting target terpenoid profiles—such as high limonene or elevated myrcene—to reinforce these traits in subsequent generations. Understanding terpenoid inheritance helps breeders predict and stabilize aroma characteristics, essential for maintaining strain identity and consumer consistency across seed production runs.
