Phytochemical Inheritance

Phytochemical inheritance refers to the genetic transmission of volatile and non-volatile compounds—terpenes, flavonoids, cannabinoids, and other secondary metabolites—from parent plants to offspring. In cannabis breeding, this trait is fundamental to strain development, as breeders select for specific chemical profiles across generations. Lineage records frequently report that phytochemical expression varies based on both genotype and environmental conditions, making selection challenging but predictable over multiple generations. Understanding phytochemical inheritance patterns allows breeders to stabilize desired aromatic and chemical signatures within seed lines. This concept underpins modern cultivar stability and consistency in cannabis genetics.

Breeders working in this category employ phytochemical profiling (gas chromatography, mass spectrometry) to track terpene and cannabinoid inheritance across crosses. Selecting parents with complementary or dominant chemical traits allows breeders to lock in desired aromatic and potency signatures in F1 and stabilized F2+ lines.
