The presence of a translocation from Aegilops ventricosa carrying the genes for rust resistance Yr17, Lr37 and Sr38 was analysed in recently registered, mostly western European wheat cultivars in the Czech Republic. By means of a PCR marker the presence of the translocation was determined in cvs. Bill, Clarus, Clever, Corsaire, Rapsodia, and in the Czech cv. Rheia. Novel are the data for cvs. Rapsodia, Clarus and Rheia. Infection tests indicated the presence of additional leaf rust resistance genes in cultivars with the translocation, except in cv. Rheia. Segregating progenies of six crosses between cv. Renan possessing Lr37and different cultivars susceptible to leaf rust were tested for the presence of the translocation with Yr17, Lr37 and Sr38 by an infection test as well as by a molecular marker. High coincidence between the results from infection tests and those by the marker has been proved.
