520 _aLow radiation and temperatures during the winter, intermittent and terminal drought and high radiation and temperature during grain filling hinder cereal production in rainfed Mediterranean areas of North Africa and Southwest Asia. Barley (72 genotypes) and wheat (40 genotypes) nurseries are grown at ICARDA to study the physiological basis of yield and to aid in crop improvement under stress. Barley has shown a higher rainfall use efficiency in environments of less than 300 mm rainfall. Crop growth analysis was a powerful tool to indicate the timing of stress. It also indicated a higher radiation intercepting efficiency during winter and a higher crop growth rate for barley under stress. Wheat had a higher light utilizing efficiency in the more stressed sites but barley had a yield advantage. Earlier flowering and shorter grain filling are typical phenological characteristics of barley. When phenological effects and the effect of yield potential were removed by calculating a drought resistance index, barley showed the highest drought resistance. Grain C13 discrimination was strongly related to the drought resistance index.
