Rice (Oryza sativa L.) is a principle crop as the main economic importance in Vietnam, providing daily food for over 90 million people in this country. However, a large rice growing areas and rice production are being seriously affected by salinity intrusion, the threats of devastation from climate change. The need to develop salinity tolerance rice varieties to cope with adverse climate change is very imperative. In this study, based on the genome sequence databases of 36 Vietnamese rice landraces, we have identified nine Vietnamese rice landraces carrying nine SalT candidate genes with the sequence similarity to O. sativa SalT (the published GenBank: Z25811.1) which have shown salinity tolerance are included: Te Nuong, Khau mac buoc, Chan thom, Khau giang, Tan ngan, Nang thom cho dao, OM5629, Hom rau and Thom Lai landraces). Amongst them, four rice landraces, Nang thom cho dao, OM5629, Hom rau and Thom lai have revealed two fragments of deletion with six and seven nucleotides which were the most identical to the SalT reference gene. Two primer pairs have been successfully designed to identify the SalT candidate genes in Vietnamese rice landraces. This study provides useful information of salinity tolerance of some Vietnamese rice landraces for breeding programs.
