Low Degrade Phenotypes

Low degrade phenotypes refer to cannabis plants that maintain cannabinoid and terpene stability over time, resisting oxidation and degradation of compounds like THC to CBN during storage or aging. These phenotypes are of interest to breeders and seed banks because they suggest genetic factors contributing to chemical longevity in preserved flower. Lineage records frequently report certain landrace and hybrid families showing superior preservation characteristics, though the specific genetic markers remain incompletely mapped. This trait is commonly associated with particular terpene profiles and cell wall structures that may slow compound breakdown. Breeders working in preservation-focused lines often select for parents demonstrating this stability across multiple generations.

Breeders targeting seed lines for long-term storage viability or commercial preservation standards often cross-select parents from documented low-degrade families. This selection approach helps produce stock that maintains original chemical profiles across extended shelf life, relevant for seed banks, breeding libraries, and regulated producers managing inventory.
