Abstract:
Simple sequence repeat (SSR) techniques were used to identify the genetic diversity of 102 G. arboreum accessions which collected from India, Vietnam and China (Guizhou, Guangxi and Yunnan). Twenty-six pairs of SSR primers produced a total of 103 polymorphic loci among these materials and average 3.96 polymorphic loci per primer were detected. The mean effective number of alleles, the mean Nei's gene diversity and the mean Shannon's information index were 0.59, 0.2835 and 0.4361. The diversity varied among different geographic regions. The result of principal components analysis was almost consistent with that of UPGMA clustering analysis. The 102 G. arboreum accessions were clustered into 3 groups. Dianya 16 was far from others and belonged to a group with one accession.
