Abstract: The wild germplasm resources of Malus baccata ( L.) Borkh distribute widely, and have diverse types, which showed great value of research and utilization. Natural distribution and taxonomic status of wild Malus baccata ( L.) Borkh in China were summarized, the result showed that the wild germplasm resources of Malus baccata ( L.) Borkh mainly distribute in the area north of Yellow River, distribute specifically in Northeast and Inner Mongolia, Shanxi, Hebei, Henan, Shaanxi, Gansu, Tibet and Yunnan in china; Malus baccata ( L.) Borkh belongs to Rosacea Maloiedae Malus. Mill. Subgen. Mauls Sect. Gymnomeles. Koehne Ser.Baccata(Rehd.)Rehd.Now some specific resources of wild Malus baccata ( L.) Borkh who are types of cold resistance, drought resistance, barren, resistance to alkali and waterlogging were found recently. At present the study on utilization of Malus baccata ( L.) Borkh mainly concentrated on breeding of cold resistance,multi- resistant rootstock,processing and landscape utilization, it were selected that the superior lines of varieties and rootstock which can be used for the production and the promising landscape types, deep processing products were exploited. In the future, we should continue to strengthen the research on protection and utilization of the wild resources of Malus baccata ( L.) Borkh, establish a set of operational evaluation system for specific characters based on the conventional techniques and modern molecular biology methods, improve the resource utilization efficiency, and strengthen the study on identification,separation and action mechanism of functional components for laying the foundation of the comprehensive exploitation of the wild Malus baccata ( L.) Borkh.
