Parameters Utilized in Screening for Salt Tolerance in Rice (Oryza Sativa L.).

Rice is a salt sensitive crop and suffers yield losses due to increased salt concentrations in the cultivated soil or irrigated water. One of the best cost effective methods to overcome salt stress can be to combat it by growing salt tolerant rice genotypes. Screening for tolerance is an essential step to identify genotypes. Salt injury symptoms that can be observed in the yield contributing traits are utilized to analyze the level of tolerance under increasing concentrations of salt. In vivo studies under field conditions in salt affected environments and in vitro studies under laboratory experimental conditions at various growth stages of rice plant have been conducted by rice researchers throughout the rice growing nations. The article is an attempt to represent the work being carried out towards screening for salt tolerance in rice.
