Abstract

The amplified fragment length polymorphism (AFLP) procedure was applied to a diverse panel of wheat (Triticum aestivum L. em. Thell.) accessions and sixty-nine of the recombinant inbred lines (RILs) from the widely used genetic mapping population derived from the cross of Opata 85 and W7984. Most (76.8%) bands were monomorphic among T. aestivum accessions. The majority of bands monomorphic in T. aestivum also were present in the synthetic wheat parent (W7984). Ten primer pairs generated 153 polymorphic AFLP bands, 140 of which could be assigned to a chromosome location and were relatively evenly distributed on the genetic linkage map. AFLP loci in T. aestivum were distributed throughout the genome; they generally have only one detectable sequence variant; and they exhibit monogenic dominant mendelian inheritance. Frequencies of polymorphic bands in the germplasm sampled are in the range that enables informative cluster analyses as well as map-based diversity and association analysis studies. AFLP bands mapped to individual loci in the Opata 85/W7984 RIL population will frequently be polymorphic in other crosses or germplasm, irrespective of whether the band arises from the T. aestivum parent or the synthetic wheat parent.
