Abstract
A total of 16,619 ESTs sequences (SSRs) of sesame (Sesamum indicum L.) were mined from Genbank. From sequences, 156 primer pairs were designed and characterized to determine the diversity among 49 sesame accessions. Twenty SSRs were found to be polymorphic and the number of alleles ranged from two to five per locus. The allele size varied from 101 to 399 bp. The average PIC value of the 20 SSR loci was 0.72 ranging from 0.49 (SEM-12-68) to 0.90 (SEM-12-27). Dendrogram analysis grouped the 49 genotypes into five separate clusters exhibiting a genetic similarity coefficient from 0.59 to 1.0. Hence, these EST-derived SSRs markers could be useful in assessing the diversity of sesame accessions and could also help in identifying diverse parents for sesame improvement programs.
