THAILAND
RGDU was established in 2001 through the close collaboration between the National Center for Genetic Engineering and Biotechnology (BIOTEC) and Kasetsart University 's Kamphaengsaen Campus. The RGDU aims to develop important genomic tools for discovering genes underlying economic traits. Discovering genes underlying 16 target traits are on going project. In particular, two important QTLs, submergence tolerance and grain aroma, were used as model for positional cloning. Two BAC libraries from KDML105 and FR13 A were developed for physical mapping and large-scale sequencing. These candidate genes have now been under functional

investigation. The new way of breeding called ‘marker-assisted selection' is the best example of how genomic technologies may contribute to improving rice yield and qualities. One success example was the new breed of the Thai Jasmine rice namely ‘Triluck'. This is the jasmine rice with combined three new traits, submergence tolerance, bacterial leaf blight, and brown planthopper, added into its genome by the using molecular markers in the backcross breeding. MAS has been employed in rice breeding routinely in RGDU.
