In order to improve salt or alkaline tolerance in rice, expand plant area and reduce low product caused b salt or alkaline stress, a lot of researches have conducted studies on genot pe diversit , ph siolog and biochemistr , genetics and gene mapping of salt or alkaline tolerance in rice. But there is not a standard method for character-i zation and evaluation on salt or alkaline tolerance in china, w hich affects further development salt o
