Mycobiome

Mycobiome refers to the fungal community present in cannabis growing substrates and plant tissues. In breeding and cultivation contexts, breeders and researchers increasingly recognize mycobiome composition as a measurable plant trait influenced by genetics, cultivation practices, and environmental conditions. Certain cannabis genetics may demonstrate higher compatibility with beneficial fungal communities, while others show resistance patterns to pathogenic fungi. Documentation of mycobiome interactions—particularly with arbuscular mycorrhizal fungi and endophytic species—is emerging as a secondary breeding consideration alongside traditional morphological traits. Understanding mycobiome relationships is primarily relevant to substrate selection and disease management rather than direct cannabinoid or terpene expression.

Breeders working with disease-resistant cultivars may evaluate mycobiome resilience as part of phytopathology screening. Some breeding programs track fungal colonization patterns in parent stock to predict substrate compatibility and pathogen vulnerability in offspring.
