Cassava (Manihot esculenta Crantz) is an important food crop in tropical and subtropical regions of the world, with high starch content and significant industrial application value. Marker-assisted selection (MAS) is an important technology in plant breeding, especially in cassava improvement, showing great potential for application. Mas provides an efficient genetic improvement method for cassava breeding, which can accelerate the improvement process of traits, especially in key agronomic traits such as starch content and disease resistance. This study systematically reviews the relevant theories of MAS, discusses the discovery of cassava genetic markers, and highlights the role of MAS in improving the efficiency and accuracy of selection, especially in accelerating the development of new cassava varieties through case studies. Despite the technical and resource challenges, the application prospect of MAS technology in cassava breeding remains optimistic. This review aims to provide in-depth scientific reference and practical guidance for cassava breeders and researchers worldwide, and to provide directions for future research.
