Crossability of Triticum urartu and Triticum monococcum wheats, homoeologous recombination, and description of a panel of interspecific introgression lines.
Bottom Line: In a germplasm collection, rare wild T. urartu lines with the presence of T. monococcum alleles were found.In a test based on 28 interspecific introgression lines, the existence of genetic variation associated with T. urartu chromosome fragments was proven for the seed content of carotenoids, lutein, β-cryptoxanthin, and zinc.The molecular state of available introgression lines is summarized.

Mentions: The segregation of molecular markers concerning F2 plants derived from the cross ID69 × ID49, was processed by the JoinMap 4.0 program (Kyazma B.V., Wageningen, The Netherlands), to map markers used in the characterization of introgression lines (Figure 3). The obtained map contains 155 SSR marker loci without segregation distortion and distributed in seven linkage groups for a total of 984 cM, with an average value of one molecular marker every 6.35 cM. Linkage groups 1 to 7 include, respectively, 22, 28, 21, 13, 29, 16, and 19 SSR loci.
