Wheat (Triticum aestivum L. ssp. aestivum) seeds from the cultivar Mexipak and F2 of the cross SaberBeg/Mexipak and saberBeg/Mexipak/Abu-Ghraib-4 were irradiated with fast neutrons and screened for resistance to leaf rust (Puccinia recondita Rob. ex Desm.) during three generations. Thirty-eight and 226 variants showing resistant and moderately resistant reactions, respectively, were selected. Of these variants three mutants showing genetic purity and stability were studied for yield components for four successive generations. Analyses of proteins and isozymes along with chemical and physical properties were conducted on these mutants and their parents. Data on disease incidence, lodging, shattering and yield components indicated that all the mutants significantly surpassed the cultivars Mexipak, SaberBeg and Abu-Ghraib-4. Both mutants Tamuz-1 and Tamuz-2 surpassed Mexipak in bread-making quality, while the mutant Tamuz-3 had a higher tendency for better bread-making quality than Mexipak or SeberBeg
