Post Harvest Genetics

Post-harvest genetics refers to the phenotypic expression and stability of cannabinoid and terpene profiles after harvest, drying, and curing—distinct from living plant expression. Environmental factors during drying (temperature, humidity, light exposure) and storage conditions significantly influence terpene retention and degradation pathways. Breeders and seed companies study post-harvest stability to understand which genetic lineages maintain consistent aromatic and chemical profiles across production cycles. This trait is particularly relevant for commercial breeding programs seeking reproducible end products. Post-harvest genetics also encompasses how specific cultivars' terpene compositions shift during the cure, including oxidative processes that create secondary aromatic compounds. Understanding this genetic component helps distinguish between true genetic potential and temporar

Breeders select for post-harvest stability by testing preserved flower samples over time, identifying lines that maintain terpene profiles rather than rapidly degrading or shifting. Seed companies use post-harvest genetics data to predict storage longevity and consistency across different grower environments.
