Drought Tolerance Traits

Drought tolerance in cannabis refers to genetic and physiological traits that enable plants to maintain function under water-limited conditions. These characteristics—including deep root systems, waxy cuticles, and stomatal regulation—are polygenic traits influenced by both environmental factors and inheritable genetic markers. Breeders working in arid regions or developing resilient cultivars often select for parent plants demonstrating reduced water requirements and stress recovery capacity. Lineage records frequently report that certain landrace populations from dry climates carry enhanced drought-adaptive phenotypes. Understanding these traits is essential for breeding programs focused on resource efficiency and environmental adaptation.

Breeders incorporate drought tolerance selection to develop cultivars suited to water-scarce environments and to reduce cultivation inputs. Parents showing consistent performance under deficit irrigation conditions are valuable for creating stable, resilient F1 and F2 generations.
