In this study, 14 agronomic traits and 139 SSR loci, distributed on 20 linkage groups of soybean (Glycine max L.) cultivar Suinong 14 and its pedigree were analyzed to explain the genetic diversity and recombination of Suinong 14 and to provide useful information for breeding. The cluster analysis based on SSR makers agreed with the pedigree information. The Shannon-Weaver index of each SSR locus ranged from 0 to 1.677. The average genetic similarity coefficient among cultivars was 0.6380, ranged from 0.538 to 0.799. At least three SSR loci were needed to discriminate Suinong 14 from its pedigree, for example a combination of Satt543, Sat_130 and Satt218. These loci have more alleles. No significant difference was observed between the end portion and the mid-portion within a linkage group, which indicates that the distribution of recombination occurred randomly in each linkage group. No polymorphism was detected within 39 of 139 SSR loci between Suinong 14 and its 8 parents. It implys their importance during cultivar improvement. Satt168, a marker on LGB2, was the only locus transmitted from Zihua 4 to Suinong 14, which indicates that the genetic constitute of Suinong 14 is greatly changed compared with Zihua 4 through five generations of recombination.
