Abstract:Cyclocarya paliurus as a unique tree species in china that has survived the Ice Age，has various uses in food， medicine，ecology，economy，and other aspects . In order to gain a deeper understanding and utilization of the resources of C. paliurus，and to better develop and promote C. paliurus，this article conducts a comprehensive analysis of its breeding methods，superior variety selection，growth characteristics，genetic diversity，resistance mechanisms，gene functions，and other research. It explores the development characteristics and potential of C. paliurus，and looks forward to future supe- rior variety selection，industrial development，and application value，in order to provide theoretical reference for the devel- opment ofC. paliurus resources and superior variety selection in china .
