Abstract
In this study, total 41 Vietnamese rice landraces were evaluated for their salt tolerance in the laboratory and field conditions. Amongst them, 15 landraces have shown moderate to high salinity tolerance in both screening conditions. The three landraces Chanh trui, Cuom dang 2 and Nep cuc have revealed the highest salt tolerance which were similar to the Pokkali. However, with time and levels of salt treatments, salt injury symptoms were clearly observed in all landraces with different symptoms. All plants growth parameters were remarkably reduced in all landraces under increasing salt-treated concentrations. By use of molecular marker RM217 linked with salinity tolerance QTL located on the chromosome 4, 11 landraces have been found to carry the allen involving in salt tolerance. This study has provided useful information on salinity tolerance of rice landraces for breeding programs to deal with the climate change in this country.
