Rice is a staple and widely grown crop endowed with rich genetic diversity and South Korea is one among the largest importer of both Japonica and Indica rice. As it is difficult to differentiate Korean rice varieties based on visual observation accurately, and hence these are highly prone to adulteration with look-alike imported rice varieties by the dishonest traders and stakeholders. DNA based techniques are the rapid and successful method to purge the problem of adulteration at commercial level. However, PCR analysis of imported rice genome has failed to secure all information. Here, we analyzed the InDel and SNP markers of 39 commercial Japonica and Indica rice cultivars from China, Australia, America, Thailand and India. In order to do accurate analysis, the genome of all above imported rice cultivars has been obtained from public genome database. The goals of this research are (1) to develop multiplex InDel or SNP markers based on the genome of 39 imported rice cultivars, (2) to develop integrated imported rice genomic database, (3) to develop multiplexing PCR kit based on the marker information. This research is still in progress and the preliminary results suggests that the marker information on the rice cultivars provide valuable resources for rice authentication and traceability.
