    A spontaneous interspecific Robertsonian translocation was revealed by genomic in situ hybridization (GISH) in the progenies of a monosomic 7H addition line originating from a new wheat ‘Asakaze komugi’ × barley ‘Manas’ hybrid. Fluorescence in situ hybridization (FISH) with repetitive DNA sequences (Afa family, pSc119.2, and pTa71) allowed identification of all wheat chromosomes, including wheat chromosome arm 4BS involved in the translocation. FISH using barley telomere- and centromere-specific repetitive DNA probes (HvT01 and (AGGGAG)n) confirmed that one of the arms of barley chromosome 7H was involved in the translocation. Simple sequence repeat (SSR) markers specific to the long (L) and short (S) arms of barley chromosome 7H identified the translocated chromosome segment as 7HL. The presence of the HvCslF6 gene, responsible for (1,3;1,4)-b-D-glucan production, was revealed in the centromeric region of 7HL.
