An octoploid triticale developed between the common wheat line 'Martonvasari 9 krl' and the rye cultivar 'Lovaszpatonai' was crossed with the 1B/1R wheat variety 'Matador'. The frequency of chromosome associations involving the 1B/1R translocation was examined at metaphase I of meiosis in BC1 plants using genomic in situ hybridization (GISH). Most of the chromosome bonds were rod bivalents (67%) and trivalents (26.6%); one quadrivalent was also observed (1.2%). The 1RS arm of the translocation chromosome paired with that of 'Lovaszpatonai' rye in only 32% of the pollen mother cells, whereas the translocated 1BL arm exhibited much higher pairing (90%) with its wheat homo(oe)logues.
