- Abstract:
- ?In this study,the genetic diversity of 40 accessions of G.tabacina,collected from Meizhou Island of Fujian province were analyzed using 20 ISSR markers to promote the protection,exploration and utilization of G.tabacina.A total of 240 bands were amplified,of which 229 bands,accounting for 95.4%,were polymorphic.The average polymorphism information content(PIC)of 20 ISSR primers was 0.27,ranging from 0.03 to 0.37.The Dice similarity coefficient of the tested accessions ranged from 0.335 6 to 0.863 9,and averaged 0.675 3.The tested G.tabacina were clustered into four groups by using the unweighted pairgroup method with arithmetic averaging(UPGMA),and each group contained one or more accessions from different collection sites.Results suggest there is rich of genetic diversity among the accessions of G.tabacina,and existing gene exchange among G.tabacina ?accessions from different collection sites.
