Drought Tolerance

Drought tolerance in cannabis refers to genetic traits that enable plants to maintain productivity under water-limited conditions. These characteristics typically include deep root systems, waxy leaf cuticles, and efficient stomatal regulation—mechanisms that reduce transpiration loss and extend viability during periods of low water availability. Lineage records frequently report drought-tolerant traits emerging from landraces developed in arid regions, including parts of Central Asia, the Middle East, and North Africa. Breeders working in water-scarce environments or seeking climate-resilient cultivars often prioritize these genetic markers. Understanding drought tolerance is relevant for both outdoor cultivation in variable climates and for developing regionally adapted breeding lines.

Breeders select for drought tolerance to reduce irrigation inputs, increase yield stability in inconsistent growing conditions, and preserve plant vigor during seasonal stress. These traits are particularly valuable in breeding programs targeting semi-arid climates or sustainable outdoor cultivation systems.
