Apple rootstock breeding has achieved great progress worldwide. In this review, we first summarize the rootstock breeding targets and utilization in main apple-producing countries. Furthermore, we discuss the focus and important research areas of apple rootstock breeding through five aspects: parent selection and setting of crosses, target genes and marker-assisted breeding, root configuration-guided breeding, apomictic resource utilization, and the application of genetic engineering. Finally, we propose an apple rootstock division plan for China, which has a large potential to provide guidance for apple rootstock breeding and utilization in different apple-producing areas of China.
