Research progress of cotton molecularmarker-assisted breeding

Molecular marker technology is one of the most important auxiliary means of cotton genetic breeding, whichhas made a significant progress in cotton molecular marker breeding research. This article gave an overview of the researchprogress in analysis of genetic diversity, prediction of heterosis, identification of germplasm, genes mapped and markerassistedselection breeding. In addition, problems appearing in the application process of cottom molecular markertechnology would be discussed in order to expect it to be better used in genetic breeding, which would provide morepowerful auxiliary means for selecting and cultivating new cotton cultivars that possessed superior multiple traits
