Title	C-banding analysis on wild Emmer (Triticum dicoccoides Korn) strains with and without spontaneous reciprocal translocations
Journal	Theoretical and Applied Genetics
Year	1996
Volume	92
Pages	173-178
Author	Taketa S Kawahara T
Abstract	C-banding polymorphism was analyzed in eight strains of wild Emmer, Triticum dicoccoides Korn, which included six translocation homozygotes reported previously Polymorphisms were detected in all of the strains examined, and the breakpoints of five spontaneous translocations were successfully identified by C-bands Of the eight breakpoints that could be precisely identified, one was located in the centromeric region while the remaining seven were located in proximal to distal euchromatic regions The two breakpoints of one translocation could only be approximately localized to proximal regions due to the scarcity of C-bands The present results are in contrast with those observed on T araraticum, another wild tetraploid wheat belonging to the Timopheevi group, in which most of the breakpoints were located in centromeric regions. In T. dicoccoides, the six translocation chromosome types were derived from the standard karyotype primarily by a mechanism other than centric breakage-fusion.
