Remotely sensed infrared canopy temperatures provide an efficient method for rapid, non‐destructive monitoring of whole‐plant response to water stress. Field studies were conducted in 1992 and 1993 to evaluate the potential for using canopy temperatures to screen for drought tolerance in wheat. In both years, 12 spring wheat (Triticum aestivum L.) genotypes were grown under two irrigation levels (well‐watered and moisture‐stressed) imposed between tillering and anthesis with a line‐source sprinkler irrigation system. Canopy temperature measurements were taken in well‐watered and moisture‐stressed plots between 1330 and 1430 h (MDT) on five clear days in 1992 and seven clear days in 1993 during the late vegetative and early reproductive growth periods following closure of the plant canopy. Genotypes exhibited differences in mean canopy temperatures across the two irrigation levels and two years. Klasic consistently had the highest canopy temperature under moisture‐stressed conditions, while Bannock and Pondera had the lowest. Bannock, Yecora Rojo and Klasic had the warmest canopies under well‐watered conditions, while Vandal, Amidon and Rick had the coolest. Plot‐to‐plot variation in canopy temperature under water stress conditions was evident for differences in grain yield. Significant correlations between canopy temperature and yield under moisture‐stress conditions and drought susceptibility index values indicated the potential for screening wheat genotypes for drought response.
