[The use of AFLP technique for the study of genetic diversity in peanut bradyrhizobia].
A total of 146 bradyrhizobial strains including 133 peanut bradyrhizobia isolated from different regions and 13 reference strains representing B. japonicum and B. elkanii were studied for their genetic diversity by use of AFLP marker technique. The genomic similarity was analysed by numerical Taxonomy based on the AFLP patterns. The results showed that the genetic diversity of peanut bradyrhizbia were very high. Each strain had a identical AFLP pattern. AFLP technique is simple, fast, highly reproducible, and is a useful tool for evaluating genetic diversity.
