That indicated the availability of SRAP technique in studying genetic variability in Arachis. Estimates of genetic distance among the 28 accessions Arachis section ranged from 0.12 to 0.75 with average genetic distance of 0.42. A genetic distance clarified that A-genome A. duranensis was most closely associated with tetraploid germplasm, which could be A-genome donors. Dendrogram of cluster analysis classified 28 accessions Arachis section into two groups: one including tetraploid germplasm, and A.
