Low Resin Phenotypes

Low resin phenotypes are cannabis plants that produce noticeably reduced quantities of trichomes and secondary metabolites compared to their parent lineages. These phenotypes arise from recessive genetic expression or environmental stress conditions, resulting in minimal crystalline coating on flowers and leaves. While less common in commercial cultivation, low resin expressions appear across many established strain families and are of particular interest to researchers studying cannabinoid and terpene biosynthesis pathways. Breeders working with these phenotypes often document them as unusual expressions within otherwise resin-heavy crosses, providing genetic markers for understanding terpene and cannabinoid production mechanisms.

Low resin phenotypes serve as valuable genetic references for isolating and studying the genetic loci controlling resin production and secondary metabolite accumulation. Some breeders intentionally select and stabilize these traits to explore alternative cannabinoid expression patterns or to develop cultivars with different agronomic or processing characteristics.
