Abstract: For improving apple dwarf rootstock breeding, its study status in China is summarized from dwarf germplasm resources, breeding effect, preselected indices of seedling, breeding problem and etc. Crossbreeding, selection breeding of strain lines, selecting by seedlings are chief methods of apple rootstock breeding in China now, better series applied to production are selected, such as SH series, Y series,‘GM256’ and so on. Gene project breeding and molecular marker assisted breeding are studied and have great progress. Preselected indices which could be applied in crossbreeding seedling, such as ratio of xylem and phloem, shoot electron resistance, POD enzyme and hormones, are screened out. Dwarf property of offspring should be forecasted combined with many preselect indices, not by an individual index. Some problems are analyzed including inadequate rootstock breeding system and modern breeding technology, weak breeding ability and etc., and the breeding prospect of apple rootstock is discussed.
