Botrytis Resilience

Botrytis resilience refers to a plant's capacity to resist or tolerate Botrytis cinerea (gray mold), a common fungal pathogen affecting cannabis cultivation. This trait family encompasses genetic markers and phenotypic characteristics—such as lower flower density, improved air circulation within canopy structure, and faster bud maturation—that breeders associate with reduced susceptibility to this mold. Resilience to botrytis is often polygenic, influenced by multiple genes rather than single-trait inheritance. Lineage records frequently report this trait in strains developed in humid climates or breeding programs prioritizing disease tolerance. Understanding botrytis resilience helps cultivators and breeders select genetics suited to their growing environment and disease pressure profiles.

Breeders working in high-humidity regions or indoor operations actively select for botrytis-resilient genetics to reduce crop loss and minimize fungicide inputs. This trait is often combined with other disease-resistance markers and structural phenotypes that support airflow.
