A number of chromosomes from species related to wheat carry genes of potentially high agronomic value. However, wheat lines carrying an additional pair of such chromosomes have never been exploited commercially because they are unstable and the extra chromosomes are frequently lost during gametogenesis. In order to overcome this problem translocations involving the long arm of the Aegilops sharonensis chromosome 4S1, which carries the gene(s) determining preferential transmission, and the long and short arms of chromosome 1U from Aegilops umbellulata, which carry respectively the genes Glu-U1 and Gli-U1, which affect bread making quality, have been isolated. These translocations are stable and preferentially transmitted.
