Abstract: Heterosis is one of the main ways that can improve the crop yield,stress resistance and quality. The sterile/recovery(CMS/Rf)system is widely used in crop heterosis. Studying the recovery mechanism of cytoplasmic male sterile lines is an important basis of molecular genetic in the selection of the ‘three lines’ breeding program. Currently,different types of sterile lines have been created in major crops. Aiding of molecular technology,genomics and sequencing technology,many fertility-restoring genes have been located,and some of them have been cloned and functionally identified. This paper systematically summarizes the genetic model and molecular marker localization,cloning and application of CMS/Rf system in hybrid breeding in the main crops. It is aimed that this paper may provide ideas for molecular marker assisted selection,transgenic or gene editing methods to create new restorer lines in the future.
