Drought Tolerance Phenotypes

Drought tolerance phenotypes represent genetic expressions that enable cannabis plants to maintain growth and function under water-limited conditions. These traits are observed across various lineages, particularly those originating from arid or semi-arid regions, and are characterized by physiological adaptations such as reduced leaf surface area, deeper root development, and efficient water-use mechanisms. Breeders working in regions with limited water availability or seeking resilience traits have increasingly documented these phenotypes in modern cultivars. The expression of drought tolerance involves complex interactions between multiple genes and environmental factors, making it a polygenic trait that varies significantly across individual plants and growing conditions. Understanding these phenotypes is valuable for agricultural sustainability and breeding programs focused on envir

Breeders targeting drought-tolerant cultivars select for water-efficient phenotypes to develop lines suitable for low-water regions and sustainable production systems. These traits are particularly relevant in breeding programs addressing climate variability and resource constraints.
