An AFLP marker catalogue is presented for gene mapping within cultivated potato. The catalogue is comprised of AFLP fingerprint images of 733 chromosome-specific AFLP markers which are mapped relative to 220 RFLP loci, isozyme loci, morphological characteristics and disease resistance traits. Use of the catalogue is based on identification of common AFLP markers which are visually recognized on autoradiogram images as co-migrating bands in fingerprints generated from different genotypes. Images of AFLP fingerprints combined with detailed information on the genomic location of all AFLP markers are available at URL: http://www.spg.wau.nl/pv/aflp/catalog.htm. It is demonstrated that the comparison of autoradiogram images and subsequent identification of common AFLP markers solely are efficient means for alignment of linkage groups and mapping target genes.
