The sample of 139 varieties of common wheat (Triticum aestivum L.) predominantly Serbian winter wheat varieties originated in the Institute of Field and Vegetable Crops in Novi Sad (Yugoslavia), has been examined for presence of 1Bl.1Rs wheat-rye translocation. The presence of translocation has been established in 40% of genotypes in study. Two genotype groups consisted of varieties possessing and lacking the translocation have been compared for biological properties behavior. Namely, stem rust, leaf rust, powdery mildew as well as, winter hardiness have been under the study. The influence of 1Bl.1Rs translocation has been studied per se, as well as, in a light of wheat grain storage protein (glutenin and gliadin) genetic background composition. Genetic composition for alleles in question has been screened using SDS-PAGE, and A-PAGE electrophoresis. The presence of the translocation has been rechecked using C-banding technique. Genotypes having the translocation appeared to be more tolerant to stem rust, and leaf rust (as a trend), but more susceptible to powdery mildew. These effects have been slightly modified depending on examined genetic background, but the efffect of 1Rs chromosomal translocated segment has been the main cause for the observed differences.
