“…These loci in Japan and China were all polymorphic (99%), and the A was the same A p as in this study. The A p and A e genetic parameters were much higher than measures using isozymes reported in wild soybean in Japan, China and Korea (Kiang et al 1992;Yu and Kiang 1993;Pei et al 1996;Fujita et al 1997), showing that molecular markers could display more genetic variation and provide more genetic information.…”

“…The genetic diversity patterns of wild soybean have been evaluated on the basis of enzymes for natural populations in Japan (Kiang et al 1992;Fujita et al 1997), China (Pei et al 1996), and South Korea (Yu and Kiang 1993), and the patterns have also been revealed by RFLP, RAPD, SSR and AFLP markers to probe the genetic differences between wild and cultivated soybeans or for the origin and dissemination of soybeans (Maughan et al 1995;Rongwen et al 1995;Kisha et al 1998;Shimamoto et al 1998Shimamoto et al , 2000Thompson et al 1998;Brown-Guedira et al 2000;Tian et al 2000;Li and Nelson 2001;Xu et al 2002;Abe et al 2003). These studies have displayed higher levels of genetic diversity in wild soybean.…”

The wild soybean, an annual self-pollinating plant, is the progenitor of soybeans and is extensively distributed in the Far East of Russia, the Korea peninsula, China and Japan. Geographically, Japan is surrounded by sea and insulated from China. We preliminarily evaluate whether the Japanese and Chinese wild soybean germplasm pools are genetically differentiated from each other using SSR markers. The results showed that the two pools have great genetic differentiation. Some loci presented obvious differences in mean genetic divergence (G ST ) value between the two pools. The G ST among the geographic regions in China was higher than that in Japan. The average within-geographic region gene diversity values (H S ) in the two pools were completely identical and thus the genetic difference between the two pools was mostly attributed to the relatively high level of between-geographic region gene diversity (D ST ) in China. We suggest that Japanese and Chinese wild soybeans should be comparatively independently evolving in phylogeny.

“…The cultivated soybean is one of the world's most important crops, with autogamous procreation system and outcrossing rates of less than 3.0% (Caviness 1966;Ahrent and Caviness 1994). The wild soybean is annual herbaceous plant with outcrossing rates of 2.4-19% (Kiang et al 1992;Fujita et al 1997) and is extensively distributed in the eastern Asia, the Far East of Russia, the Korea peninsula, the eastern half of China, and Japan.…”

Introgression from soybean cultivars to its wild progenitor species is an interesting antidromic recombination in natural ecosystem with many consequences, including the alteration of genetic diversity, the origin of semi-wild soybean, and implication for biosafety of the wild progenitor species with future release of the genetically modified varieties. Although such interspecific introgression is not suspected to be ubiquitous in the sympatric regions of wild and cultivated soybeans, the documentations published based on some molecular experimental analyses on the introgression have been little substantiated by the occurring process morphologically and remain deficient for unquestionable evidence, owing to the lack of actual insight into the population dynamics. Here, we found the phenomenon of gene escape and presented the evidence for occurrence of introgression from soybeans into the wild species and for how originates about the semi-wild type soybean based on morphological investigation of population dynamics. Our results suggest that more attention should be paid to the escape of genetically modified genotypes to safeguard the biosafety of wild soybean gene pool, if GM soybeans are released in China, the place of origin of cultivated soybeans.

“…Yu and Kiang (1993) demonstrated that South Korea might be one of the major soybean gene centers in a study of 17 enzymes and one non-enzyme protein from annual wild soybeans that came from six natural populations. Kiang et al (1992) studied four natural populations of G. soja by analyzing 15 enzymes and one non-enzyme protein and showed that genetic diversity was 0.07 and 0.3 between-and withinpopulations, respectively, and that the coefficient of differentiation among populations was 0.2. Vaughan et al (1995) analyzed the genetic diversity of ten annual wild soybean populations collected within a 20-km radius of Tsukuba using randomly amplified polymorphic DNA (RAPD) analysis and found a relatively high degree of local variation for G. soja on the Kanto plain and a mosaic of variation rather than small-scale clonal variation.…”

Cultivated soybean ( Glycine max) is an economically important crop that is grown for its oil and protein products. A better knowledge of its genetic diversity will be valuable for the utilization, conservation, and management of germplasm collections. Using the database of the National Germplasm Evaluation Program of China (NGEPC), we studied the geographical distribution of accessions, the genetic diversity of 15 qualitative and quantitative characters, and the genetic diversity centers of cultivated soybean in China using variation in these 15 traits and genetic diversity indexes (Shannon index). Cultivated soybean is widely distributed throughout China. As an indication of its distribution, a line can be roughly drawn from the Daxinganling mountains in northeastern China to the Qingzang plateaus in southwestern China based on the abundance of accessions and locations of the collections. Of the 22,637 known accessions in China, the 20,570 collected over a vast area between latitudes 18 degrees and 53 degrees N and longitudes 80 degrees and 136 degrees E were used in this study. The Shannon indexes of various morphological traits were calculated. Cultivated soybean accessions were found to exhibit a higher genetic diversity in the area between 34 degrees -41 degrees N and 110 degrees -115 degrees E. On the basis of the geographical distribution of a number of accessions, and their genetic diversity, one genetic diversity center-downstream of the Yellow River Valley-is proposed. Based on these results and on Vavilov's theory on crop origins, one possible diversity center was proposed.
