| 520 | _aDrought is the main factor affecting crop grain yield in many semi-arid and arid regions of the world. Increasing grain yield rmder drought and crop water use efficiency are essential for enhancing crop production in water-limited envirornnents. The aim of this study was to determine the relationship between kernel ash, water use efficiency and grain yield of dururn wheat genotypes nnder water deficit conditions induced at three growth stages. The result revealed that water deficit significantly affected grain yield, biomass yield, harvest index, kernel weight, kernel number per spike, kernel ash content and water use efficiency. Kernel ash content was negatively and significantly correlated with grain yield and WlJE rmder the prolonged water deficit induced at|tillering and anthesis stages and such relationship did not appear rmder moderate water deficit induced at grainfilling stage and well-watered control. The relationship between kernel ash and 100-kernel weight was consistently negative and significant in all water regimes. On other hand, kernel ash content was positively correlated with drought susceptibility index rmder severe water deficit showing that susceptible genotypes|during grain-filling accumulated more minerals in their kernels. The study result suggested that ash content in kernels is a useful physiological tool for assessing yield performance and water use efficiency in dunun wheat under severe water deficit conditions. | ||
