[Microsatellite marker development and applications in wheat genetics and breeding].

Microsatellites are simple, tandemly repeated one to six nucleotide sequence motifs. They are very useful as genetic markers because they are co-dominant, detect high levels of allelic diversity, and are easily assayed by the polymerase chain reaction ( PCR ). In wheat, SSR markers have been applied to genetic mapping,detection of genetic diversity, identification of varieties and genotypes,gene tagging, QTL analysis, and marker-assisted selection.
