EVALUATING SALINITY AND SUBMERGENCE TOLERANCE IN DIFFERENT LOCAL RICE VARIETIES

Abstract

Investigating abiotic stress tolerance from local rice varieties is necessary in order to obtain breeding materials which could be used for rice breeding to cope with climate change. In present study, 15 local rice varieties were examined for submergence and salinity tolerance. We identified Tieu Phat is highly tolerant to both stresses. Furthermore, we also found that Nang Quot and Doc Phung are salinity tolerance and Lua Nuoc Man is submerged tolerance. These varieties have large potential in rice breeding to expand rice production areas to coastal regions.
