Necrosis Phenotype
The Necrosis Phenotype refers to a genetic expression in cannabis characterized by leaf darkening, spotting, or tissue death that appears during flowering or late vegetation. This trait is often associated with anthocyanin accumulation, nutrient stress responses, or specific recessive alleles, and appears across multiple unrelated lineages rather than as a single family marker. Breeders and cultivators document necrotic patterns for phenotype identification and stability assessment, though the underlying genetics remain incompletely mapped. Environmental factors—cold, phosphorus availability, light intensity—strongly influence expression, making necrosis phenotypes useful markers for stress-response breeding programs.

Necrosis phenotypes serve as visual markers for identifying stable or heterozygous lines, and some breeders intentionally select for cold-tolerance or nutrient-efficiency traits that co-express with mild necrotic patterning. The trait's sensitivity to growing conditions makes it valuable for research into genotype-by-environment interactions.
