Abstract: Breeders in early stage of plant improvement tried to select traits of interest by observation and direct selection from phenotypic performance of individuals in the field. However, the challenge for current plant breeding is an integration of modern technology, such as biotechnology with a conventional method. One example is the utilization of molecular markers in order to improve selection efficiency. The advantage of marker-assisted selection (MAS) is that breeders can select for progenies which a recurrent genome recovery can be obtained faster and more effective than a conventional method. Further more, marker-assisted selection technique is very useful for selecting traits that are difficult and time consuming to select under field conditions. The objective of this study is to improve the ability to tolerate submergence in a rice cultivar RD6 by introgressing the sub1 gene from the donor KD571-77 through a backcross breeding method. Three flanking SSR markers for the sub1 gene on chromosome 9 were used. These markers included RB0873, RM219 and RM285. The results showed that in the BC1F1 and BC2F1 generations, 16 and 26 plants were identified carrying the sub1 gene, respectively. Currently, the BC3F1 generation was allowed to self- fertilize to produce a BC3F2 generation. This population will be grown for selection of plants carrying a target gene in the next season. The near-isogenic lines obtained from this project will be evaluated for submergence tolerance and other agronomic characteristics, then released to farmers in the flood-prone areas in the Northeast.
