Based on the analysis of the status of apple trade and production, and the construction of 4 apple germplasm resources repositories in China , the advances in research on the collection and conservation of Malus Mill. resources are summarized. The techniques for apple germplasm resources identification and evaluation are described, which include the identification and evaluation of agronomic and quality characteristics, dwarfing characteristics, apomictic capacity and so on. The data of the identification and evaluation for 501 accessions of apple germplasm resources have been processed with modem computer techniques, and mutually informative databases of apple germplasm resources have been established. At present the creation and use of apple germplasm resources are embodied in three major respects, such as breeding of new apple cultivars, new dwarfing rootstocks and utilization of apomixis of species in Modus Mill. The programs and emphasis of research on apple germplasm resources in China are suggested.
