Highly polymorphic markers such as simple sequence repeats (SSRs) or microsatellites are very useful for genetic mapping. In this study novel SSRs were identified in BAC-end sequences (BES) from non-contigged, non-overlapping bacterial artificial clones (BACs) in common bean (Phaseolus vulgaris L.). These so called “singleton” BACs were from the G19833 Andean gene pool physical map and the new BES-SSR markers were used for the saturation of the inter-gene pool, DOR364×G19833 genetic map. A total of 899 SSR loci were found among the singleton BES, but only 346 loci corresponded to the single di- or tri-nucleotide motifs that were likely …
