Terpene Inheritance Basics

Terpene inheritance in cannabis follows Mendelian and polygenic patterns, with terpene profiles shaped by multiple genes rather than single loci. Breeders have identified that dominant and recessive alleles control the production of primary terpenes like myrcene, limonene, and pinene, though expression remains influenced by environmental factors including temperature, light, and soil chemistry. Lineage records frequently report that F1 hybrids often display intermediate or dominant terpene expressions from parent plants, while subsequent generations show increased variation. Understanding terpene inheritance helps breeders stabilize aromatic traits across generations and predict offspring aromatic profiles based on parent genetics. This foundational knowledge supports intentional breeding programs designed to concentrate or diversify volatile compound production.

Breeders working in this category select parent plants with desirable terpene profiles and track aromatic stability across multiple generations to establish true-breeding lines. Terpene-focused selection has become central to cultivar development, allowing breeders to document and reproduce consistent aromatic signatures within families.
