Low Resin Phenotype

Low resin phenotype describes cannabis plants that produce minimal trichome density and cannabinoid/terpene yield compared to standard cultivars within the same genetic family. This trait is typically polygenic, influenced by multiple genes and environmental factors including light intensity, nutrient availability, and stress conditions. Low resin phenotypes may arise from recessive alleles, incomplete dominance patterns, or environmental suppression during flower development. While uncommon in modern commercial breeding, these phenotypes occasionally emerge in large seed runs or hybrid crosses and are documented in heirloom and landrace genetics. Understanding resin expression helps breeders stabilize high-yielding lines and identify genetic markers associated with trichome development.

Breeders typically cull low resin phenotypes during selection to maintain cannabinoid and terpene potency in target lines. However, studying these plants can reveal recessive genes affecting trichome formation, helping refine breeding strategies for resin production optimization.
