Environmental Genotype Interaction
Environmental Genotype Interaction (EGI) refers to the phenomenon where a cannabis plant's expressed aroma profile shifts based on growing conditions, despite carrying the same genetic blueprint. Temperature, humidity, light spectrum, soil composition, and nutrient availability can all influence which terpenes are produced and in what ratios. This means two clones of the same cultivar grown in different environments may develop noticeably different aromatic characteristics. Understanding EGI is critical for breeders and cultivators seeking consistent phenotypic expression, as it explains why stable genetics sometimes yield variable results across facilities.

Breeders working toward aroma stability must conduct multi-environment trials to identify which terpene profiles are genetically fixed versus environmentally triggered. This data informs selection strategies for creating cultivars with robust, predictable aromatic expression across diverse cultivation systems.
