Abstract: Cotton is an important cash crop. Since it is difficult to improve the yield and quality of cotton simultaneously using conventional breeding methods, combination of genetic engineering method and conventional breeding method is a practical approach to improve the quality of cotton fiber quality currently. This paper summarized the process of fiber development of cotton, and reviewed the specific genes and promoters involved in fiber development, so as to provide references for improving the quality of cotton fiber by means of genetic engineering method.

Key words: fiber, specific genes, promoters
