Intergenomic translocations between wheat, Hordeum chilense and Hordeum vulgare have been obtained in tritordeum background. Advanced lines from the crosses between three disomic chromosome addition lines for chromosome 2H v , 3H v , and 4H v of barley ( Hordeum vulgare ) in Triticum aestivum cv. Chinese Spring (CS) and hexaploid tritordeum (2n = 6x = 42, AABBH ch H ch ) were analyzed. Multicolor FISH using both genomic DNA from H. chilense and H. vulgure were used to establish the presence and numbers of H. vulgure introgressions into tritordeum. Interspecific H. vulgare/H. chilense and intergeneric wheat/ H , vulgure and wheat/ H , chilense translocations were identified. Frequencies of plants containing different kinds of intergenomic translocations between chromosome arms are presented. These lines can be useful for introgressing into tritordeum characters of interest from H. vulgure.
