Terpene Heritability

Terpene heritability refers to the genetic consistency with which aromatic compounds pass from parent plants to offspring in cannabis breeding programs. Breeders track terpene profiles across generations to understand which volatile compounds breed true and which vary with environmental conditions. This concept bridges classical genetics and phytochemistry, helping breeding teams predict aromatic outcomes and stabilize desired scent characteristics in seed lines. Heritability estimates vary widely—some terpenes like myrcene show relatively high heritability in certain lineages, while others fluctuate significantly based on phenotype expression and growing conditions. Understanding terpene heritability is critical for establishing IBL (inbred line) stability and maintaining strain identity across multiple generations.

Breeders use heritability data to design selection protocols, prioritizing parent plants that consistently express target terpene profiles. Stabilized lines with high terpene heritability command market attention because they deliver predictable aroma and flavor characteristics across commercial cultivation environments.
