Linkage map of T. monococcum (outer circular segments) based on 121 F₂ individuals of the ID 49 × ID 69 mapping population, and representation of the introgression lines of T. urartu ID388 in T. monococcum L118 anchored to linkage groups. For each of the seven linkage groups, the map positions of the corresponding molecular markers are reported. Black bars represent single chromosome segments of T. urartu detected in the introgression lines, while bars with the same color point out multiple chromosome segments of T. urartu detected in a single introgression line. Chromosome segments of T. urartu were anchored to ID 49 × ID 69 linkage map of einkorn when segregating in coupling together with specific chromosome A^m markers (see the section Materials and Methods). The recent sequencing of the T. urartu genome (Ling et al. 2013) will, in the future, allow a more precise definition of the recombination sites between A^u and A^m chromosomes.
