This document discusses a study assessing the impact of key physiological traits on wheat adaptation to contrasting drought environments. The objectives were to (1) assess the relative impact of traits on different drought environments, (2) develop a field-based phenotyping system to estimate seasonal water use, (3) evaluate elite drought-adapted lines from ICARDA, and (4) build phenotyping capability. The study analyzed traits from 245 lines in 38 environments across countries. Results showed specific adaptation of traits like flowering time and tillering to different drought types. Phenotyping methods were developed and workshops held to build capacity in the region.
