The Kazusa DNA Research Institute and Kyushu Okinawa Agricultural Research Center, NARO in collaboration with the Chinese Academy of Agricultural Sciences, China Agricultural University, Korea Research Institute of Bioscience & Biotechnology, and Rural Development Administration of Korea established the first high-density genetic map of hexaploid sweet potato (Ipomoea batatas) using SNP markers identified by double-digest restriction site-associated DNA sequencing based on next-generation sequencing technology. The sequence reads were aligned onto the reference genome sequence of wild type Ipomoea trifida, a likely diploid ancestor of sweetpotato and were used to detect the difference in the sequence between the two genomes. The results will provide basic information for comprehensive analysis of the hexaploid sweet potato genome and for breeding of improved sweetpotato cultivars.
