Salinity Tolerance-2000
Project Leader and Principal UC Investigators Jan Dvorak, professor, Department of Agronomy & Range Science, UC Davis	The official title of this project is Enhancement of Osmotic (Salinity) Stress Tolerance in Rice. What it means is that scientists are trying to develop a more thorough understanding of the mechanisms that control salinity tolerance in California rice, an issue of concern in some parts of the Sacramento Valley. With the help of the International Rice Research Institute in the Philippines, scientists have identified the top known source of salt stress tolerance from the Indica rice variety Pokkali. Genetic mapping utilizing crosses of Pokkali with a salt sensitive variety enabled scientists to identify genetic markers linked to salt tolerance. Further work has enabled them to improve the precision of the map and position of the "Saltol" gene. The process of transferring this tolerance into California is taking place by crossing and backcrossing Pokkali with M-202.
