dc.description.abstractSesame (Sesamum indicum L.) belongs to the Pedaliaceae family. It is an important oil seed crop which is cultivated in tropical and subtropical areas of Asia and Africa. China is the largest producer of sesame seed in the world while Turkey ranks seventh and produces 21036 tonnes of sesame seed in a year. Although sesame's edible seed and high quality seed oil are important for both humans and the economy, there is not enough information about the sesame genome in the literature. Our aim was to determine the diversity of 158 Turkish sesame accessions by using the AFLP marker system and to design a new set of sesame-specific SSR markers from genomic sequence of S. indicum. The Turkish sesame accessions were tested with five AFLP primer combinations, as a result, 148 polymorphic fragments were obtained. The maximum similarity was 57% for the accessions and a good level of diversity was present in the sesame germplasm. Secondly, a genomic library of sesame was constructed. A total of 1.094.317 reads were obtained and 702.371 of them were clustered to 140.669 reads containing 93.365 nucleotides. A total of 3101 primer pairs were developed from flanking regions of SSRs with primers for dinucleotide (36,4%), tetranucleotide (29,3%), trinucleotide (23,1%), pentanucleotide (7,1%), and hexanucleotide (4,2%) repeats. These primers are the first genomic-SSR markers developed for sesame cultivars. SSRs have good reproducibility, high genome coverage, co-dominant inheritance, good transferability to close species and are multiallelic. The designed genomic-SSRs should be very useful for sesame mapping and diversity studies.en
