Abstract
One hundred and seventy-eight loci have been mapped in Triticum tauschii (Coss.) Schmal. (2n = 14, DD) and Triticum aestivum L. em. Thell. (2n = 42, AABBDD). Thirty-five loci were mapped by aneuploid analysis in T. aestivum. One hundred and fifty-two loci, including 143 restriction fragment length polymorphisms (RFLPs), 8 proteins, and 1 leaf rust resistance gene, were mapped in an F2 population (60 plants) of T. tauschii. One hundred and twenty-seven loci were placed in linkage groups belonging to seven D-genome chromosomes of T. tauschii. The source of the probes was a PstI genomic library of T. tauschii, which gave 13% single-low copy clones. Four restriction endonucleases (DraI, EcoRI, EcoRV, HindIII) gave 75% polymorphism between the two parents. Nineteen clones detected multiloci ranging from two to nine in number. Deletions-insertions and point mutations were equally important for generating RFLPs. A hypervariable sequence was identified, which may have potential use in varietal fingerprinting. One marker was found to be linked to a rust-resistance gene. The map will be useful for determining genetic relationships in the Triticeae and for tagging genes of economic importance.
