Terpene Polygenic Traits

Terpene polygenic traits refer to aromatic compound profiles controlled by multiple genes rather than single genetic loci. In cannabis breeding, terpene expression is typically influenced by numerous alleles across different chromosomal regions, making the inheritance pattern complex and non-Mendelian. Breeders working with terpene selection observe that offspring terpene profiles often represent blended or novel combinations from parent plants, rather than discrete phenotypes. This polygenic control explains why terpene-rich cultivars can produce variable aromatic expressions across generations and environmental conditions. Understanding polygenic terpene inheritance has become foundational to modern cannabis breeding programs seeking consistent flavor and aroma profiles.

Breeders leverage polygenic terpene traits through selective crosses and multi-generational stabilization to accumulate desired terpene alleles. Stabilizing specific terpene combinations typically requires longer breeding cycles and larger phenotypic screening populations compared to single-trait selection.
