To study the D-genome of the wild wheat relative  Aegilops tauschii  Cosson at the hexaploid level, we developed a synthetic doubled-haploid (DH) hexaploid wheat population, SynDH3. This population was derived from the spontaneous chromosome doubling of triploid F 1  hybrid plants obtained from a cross between  Triticum turgidum  ssp.  dicoccon  PI377655 and  A. tauschii  ssp.  strangulata  AS66 × ssp.  tauschii  AS87. SynDH3 is a diploidization-hexaploid DH population containing recombinant D chromosomes from two different  A. tauschii  genotypes, with A and B chromosomes from  T. turgidum  being homogenous across the entire population. Using this population, we constructed a genetic map. Of the 440 markers used to construct the map, 421 (96%) were assigned to 12 linkage groups; these included 346 Diversity Arrays Technology (DArT) and 75 simple sequence repeat (SSR) markers. The total map length of the seven D chromosomes spanned 916.27 cM, with an average length of 130.90 cM per chromosome and an average distance between markers of 3.47 cM. Seven segregation distortion regions were detected on seven linkage groups. Out of 50 markers shared with those on a common wheat map, 37 showed a consistent order. The utility of the diploidization-hexaploid DH population for mapping qualitative trait genes was confirmed using the dominant glaucousness-inhibiting gene  W2   I   as an example.
