Technical Abstract: A high-resolution maize molecular map is being produced using RFLP and SSR markers. The mapping population is derived from a cross of B73 x Mo17 which underwent random mating for four generations. The random mating process increased the average number of recombination events per individual by three-fold compared with F2- or RI-derived mapping lines. The map presented dhere represents the initial phase of a large-scale mapping effort aimed at producing a dense, high-resolution reference map for maize. To date, more than 570 markers have been mapped. The total map length is 2.9-fold greater than the UMC 1998 Maize Genetic map. The RFLP markers employed have been pre-selected for low copy number. The loci they identify will serve as a bridge to prior map information and anchors for contig assembly of fingerprint data on a 10X maize BAC library. More than 750 cDNA or genomic clones have been screened for use in RFLP mapping. Images of the screenings sare available in the Maize Genome Database. The SSR markers provide a bridge from this map to other SSR maps and as additional anchor points for BAC contig assembly. Screening images of the SSR markers are also available in the database. All map data and associated marker information will be available through the Maize Genome Database (http://www.agron.missouri.edu).
