A 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 (Serbia, Yugoslavia), has been examined for presence of 1B1.1Rs wheat-rye translocation. Stem rust, leaf rust were studied. The influence of 1 B1.1Rs translocation has been observed in a light of wheat seed storage protein (HMW glutenin) genetic background composition. Genotypes having the translocation appeared to be more tolerant to stem rust, and in smaller extent to leaf rust. The introgression of foreign genes by means of chromosomal aberrations and classical hybridization in order to improve wheat traits still appears to be successful and ecologically justified approach.
