abstract
SSR markers, also known as microsatellite dna markers, are very useful for saturation of the large and complex upland cotton (Gossypium hirsutum L.) genetic linkage map. Monsanto has invested heavily in development of cotton SSRs and has implemented molecular breeding technologies for the genetic improvement of cotton globally and the acceleration of the integration of biotechnology traits into the most elite upland cotton germplasm in the commercial pipeline. genomic clones from microsatellite-enriched cotton DNA libraries were sequenced to identify of the tetraploid cotton genetic map. these bins contain 945 unique Monsanto SSR marker loci and 615 public anchor SSR markers. in order to contribute to the expanding genomic resources for cotton research and improvement, Monsanto is facilitating the uploading of the unique SSR primer sequences, their respective target clone sequence, and chromosome bin designation (if known) to Cotton DB (http://cottondb.org/) and CMD (http://cottonmarker.org) databases. these will be available for general use in the cotton research community without restriction.
