摘要
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.
