Abstract

The genetic diversity among twenty-six released soybean (Glycine max (L.) Merr.) varieties was examined by means of pedigree analysis. The coefficients of parentage (r) between genotypes were computed and used as indices of genetic diversity. The pedigrees of the twenty-six varieties were traced to eighteen ancestors from five geographic regions, with Japanese germplasm forming the major portion (64%) of the genetic constituents of these varieties. Wakashima (23%) and the land race Japan Ching-pi-dow (16%) were predominant in mean relative genetic contribution. The average r between varieties was 0.09. This relatively small value results from the use of diverse germplasm for variety development. Cluster analysis based on r produced six groups of varieties, but three varieties were not members of any cluster. The average r within clusters ranged from 0.33 to 0.50. Little relationship was found between clusters. Although cluster and pedigree analyses revealed that individual soybean varieties are not broadly based, reasonable genetic diversity occurs among these genotypes.
