Drought Tolerance Genetics

Drought tolerance genetics refer to plant traits and lineage characteristics that enable cannabis plants to maintain vigor under water-limited conditions. These traits are often expressed through deeper root systems, altered leaf morphology, and efficient stomatal regulation—characteristics frequently observed in landraces from arid or semi-arid regions. Breeders studying drought tolerance examine parental lines from geographic origins with naturally low precipitation, where selective pressure favored plants that conserved moisture and continued development with minimal water input. Such genetics remain largely understudied in formal cannabis breeding literature, though anecdotal breeding records and regional cultivation practices document their importance in certain lineages.

Breeders working in drought-prone climates or developing outdoor genetics often select for these traits to reduce irrigation dependency and improve resilience in water-stressed environments. Crossing drought-tolerant landrace genetics into modern cultivars is one method to introduce physiological efficiency without sacrificing yield potential, though the relationship between water efficiency and c
