One of the substainable solutions to deal with climate change causing inundation in some coastal areas of Vietnamese Deltas is to improve rice tolerance of submergence. The objective of this paper was to evaluate the tolerance submergence ability of some rice varieties imported from IRRI. The preliminary results showed that IR64-Sub1 is the best variety with tolerance of submergence ability and being used as the material in rice breeding program; TDK-Sub1 (5.9 tons/ha) and BR11- Sub1 (6.8 tons/ha) are also tolerance of submergence varieties with acceptable rice quality and having resistance with some rice diseases, which could appropriate for growing in some areas of the North and Cuu Long Deltas
