    Domestication of the crop plants has narrowed the genetic base of the crops and thereby mounting their exposure towards global climate change, disease and insect epidemics. Genetic variability of modern days crops must be broadened to make crop production more sustainable against various biotic and abiotic stresses which are posturing major threats to the world. It is therefore, crucial to identify novel additional sources of durable resistance. Wheat wild relatives have provided valuable sources of genetic diversity for various biotic, abiotic and quality components. In this respect wide hybridization has become a promising breeding method for introducing new variability in crop plants by using the crop wild relatives. In the present research work wheat-Th. Bessarabicum amphiploid, addition and translocation lines have been screened. These genetic stocks were exposed to 15% polyethylene glycerol (PEG) stress, to find out the drought tolerant addition and translocation lines by studying different physiological parameters. The screening of drought stress revealed that addition lines 2JJ, 4JJ, 5JJ, 7JJ and translocation line Tr-7 exhibited tolerance attitude towards water deficient conditions.
