Mapping population comprised 91 F`2` individuals. Position of centromere was based on telocentric analysis. A common set of probes mapped on the short arm of chromosome 1 in two populations of T. monococcum and on 1BS in populations of T. aestivum and T. turgidum revealed colinear loci. However, the XNor locus was more distal in T. monococcum than in the other species. A = CNN allele; B = CS allele; H = heterozygous; C = B or H; D = A or H; - = missing datum. Locus Xmwg2021 is completely linked to Xmwg645.1. Loci XNor, X5SDna, XcsIH69, Xpsr381, and Xabg500 are completely linked. Locus Xpsr161 is completely linked to Xbcd762.
