Abstract: There are abundant germplasm resources of Juglans in Sichuan Province, which are the important origin of Juglans sigillata. Sichuan is a natural interlaced zone between J. regia and Juglans sigillata and contains abundant excellent and special germplasm resources. Nearly 80 superior varieties were selected in different ecological regions by crossing, selection and introduction, and the regionalization of improved varieties was preliminarily completed. Combined with the trend of industry development and the characteristics of resources in Sichuan, consideration was given to the utilization of germplasm resources in the future.
