Abstract:
The collection，improvement and innovation of germplasm resources are main ways to enrich the genetic basis of soybean.The genetic diversity of 84 accession of wild soybean from Russia and Heilongjiang province，China，and 39 accession of cultivated soybean from Northeast China，was studied by SSR technique.Forty-five SSR primers were synthesized according to published data，and 12 out of them had polymorphic alleles.A total of 50 alleles were observed，the number of alleles in different loci ranged from 2 to 7，averaging 4.17 per locus，the average polymorphism information content (PIC) was 0.595.Cluster analysis showed that wild and cultivated soybean belonged to two species from the dendgrom at the site of genetic similarity coefficient 0.734，which conformed to phenotypic results.The average genetic distance of wild soybean and cultivated soybean were 0.2595 and 0.1895 respectively，which suggested that wild soybean had more polymorphism than that of cultivated soybean.Hence，wild soybean from Russia and Northeast China could be used to broaden the genetic basis of cultivated soybean in Northeast China.
