Drought is one of the most important types of abiotic stress that affects stability and amount of yield. It is well known that the proline contents in leaves of many plants get enhanced by several stresses including drought stress. Selecting barley genotypes with better adaptation to water stress should increase the productivity of barley. The purp...
