Fungal Susceptibility

Fungal susceptibility refers to a plant's genetic predisposition to develop fungal infections under favorable environmental conditions. This trait is not an aroma or flavor compound, but rather a cultivation characteristic that breeders track through phenotypic observation and environmental testing. Plants with higher susceptibility may show increased likelihood of powdery mildew, botrytis, or other fungal pathogens when humidity and temperature conditions align. Conversely, some lineages demonstrate natural resistance through genetic factors. Understanding fungal susceptibility patterns helps breeders select parent plants and develop cultivation recommendations for specific growing environments.

Breeders working in humid or high-pressure fungal environments often prioritize selecting for fungal resistance traits, crossing susceptible cultivars with those showing documented resistance. This trait guides decisions about phenotype selection and helps predict behavior across different grow operations and climates.
