Abstract:
In order to evaluate the genetic diversity of the wild soybean(Glycine soja) in the different region of Liaoning Province，China，a total of 30 wild soybean accessions from 5 ecological regions(semi-humid zone of plain in the centre，semi-humid zone of low hill in the south，semi-humid zone of plain and low hills in the northwest，semi-arid zone of hill in the west ，and humid zone of mountainous lands in the east，abbreviated as regionⅠ，Ⅱ， Ⅲ， Ⅳ andⅤ，respectively )of Liaoning province in 2007 were genotyped using 40 pair of SSR primers.129 alleles were detected by 18 pair of SSR markers，with an average of 7.2 alleles for each locus.Shannon-Weaver diversity indexes varied from 1.1753 to 2.1234 with averaged 1.7285.The region Ⅰ had the most germplasmas，the alleles and the highest genetic diversity，followed by the region Ⅴ and the region Ⅳ had the least and the lowest.The value of genetic similarity was highest(0.6496)while the value of genetic distance was the lowest(0.4314)between the region Ⅰ and Ⅴ.The value of genetic similarity was the lowest(0.4326)while the value of genetic distance was highest(0.8379)between the region Ⅲ and Ⅳ.There was no relativity between the results by the SSR markers and geographic origin by cluster analysis.
