BIOLOGICAL RESOURCES DIVISION: Characteristics and genetic diversity of soybean genetic resources in Northeast China

摘要

Northeast China is thought to be one of the regions from which soybean originated, due to the existence of a number of valuable soybean varieties in this region. Although these soybean varieties are important as genetic resources for breeding purposes, their primary characteristics and genetic diversity have not yet been clarified. Therefore, we studied the main characteristics of some 3,000 soybean genetic resources and constructed a database, aiming to improve the efficiency of their utilization as breeding stock. In addition, we evaluated their diversity to clarify the usefulness of northeast Chinese soybean genetic resources.
