Post Harvest Traits

Post-harvest traits refer to how cannabis plant material changes during drying, curing, and storage—a critical but often-overlooked area of genetics research. Factors like moisture retention, structural degradation, terpene volatility, and microbial susceptibility are partly inherited and partly environmental. Breeders working with stabilized lines have noted that some genetic backgrounds retain cannabinoid and terpene profiles more reliably than others across different curing conditions. Understanding these traits matters because they influence final product consistency, shelf life, and the expression of aroma compounds that may differ substantially from fresh plant material. Seed companies increasingly document post-harvest performance alongside flowering time and yield, recognizing that a strain's true profile emerges only after proper processing.

Breeders selecting for post-harvest stability prioritize phenotypes with dense, slow-drying architecture and robust cell structure to minimize degradation. Stability data from multi-environment trials helps inform which parent lines pass down reliable curing characteristics to offspring.
