Abstract The perennial Secale cereanum cultivar ‘Kriszta’ is an artificial hybrid of S. cereale and strictum ssp. anatolicum . From the cross between wheat line Mv9kr1 ‘Kriszta’, which aimed transfer beneficial traits from rye to wheat, numerous translocation lines have been produced. For identification translocated chromosomes, unambiguous differentiation chromosome arms essential. its short using conventional FISH probes easy, but because their similar hybridization patterns, long cannot be distinguished. present study create detailed karyotype especially that arms, by both measurements highly repetitive, as well subtelomeric tandem repeat, synthetic microsatellite DNA sequences. Our results indicate complement not a simple combination chromosomes parental species composed rearranged chromosomes. It also showed adequate pair-wise sequences pSc119.2, pSc200, pSc250, (AAC) 5 makes it possible identify any cv. Kriszta future usability identified wheat- discussed.
