Terpene Expression Genetics
Terpene Expression Genetics refers to the hereditary factors that control which volatile compounds a cannabis plant produces and at what concentrations. These genetic traits determine the terpene profile—limonene, myrcene, caryophyllene, pinene, and others—that develop during flowering and maturation. Breeders map terpene expression across generations to stabilize desired aromatic profiles and understand how environmental factors interact with genotype to influence final chemistry. Terpene phenotypes can vary significantly within a single strain family due to recessive alleles, epigenetic factors, and environmental expression triggers. Documentation of terpene expression helps the breeding community identify stable lines and predict offspring chemistry from known parent material.

Breeders working in terpene-focused selection programs cross plants with complementary terpene profiles to concentrate desired compounds or create novel terpene combinations. Consistent terpene expression is a key stability marker used alongside cannabinoid ratios when establishing IBL (inbred line) status and commercial cultivar benchmarks.
