Sesame (Sesamum indicum L.; Pedaliaceae) is a commercially valuable oilseed crop with high oil content. Furthermore, we will construct a physical chromosome map based on at least 1,000 BAC clones using information obtained from BAC-FISH and BAC-end. At present, genomic information on the Pedaliaceae family is quite limited, as genomes from this family have not previously been sequenced. Sesame (Sesamum indicum L.) is an ancient oil crop that has been referred to as the ‘Queen of oilseeds’ by the virtue of its high quality oil (Salako and Falusi, 2001). Ramanujam (1941) reported the chromosome number of another species of the same genus, S. prostratum as sixteen.
