The National Academy of Agricultural Science (NAAS) has developed a web-based genetic marker system to provide information about SNP and QTL markers in rice. The SNP marker database provides 7,227 SNP markers including location information on chromosomes by using genetic map. It allows users to access a detailed characterization table of 12,829 potential SNPs in 3,356 genes. The QTL marker database provides 175 QTL markers information with 942 polymorphic markers on each of the 12 chromosomes in rice. Users are assisted in tracing any new structures of the chromosomes and gene positional functions through comparisons using specific SNP and QTL markers.

Key words: Genetic map, rice database, SNP marker, QTL marker.
