Abstract: In order to obtain salt-tolerant rice germplasm during entire growth period, 500 rice varieties from different rice growing region were treated with 0.3% NaCl at seedling stage. Thirty-four rice varieties with their survival rate and green leaf rate exceeding 50% were screened out. The 34 rice varieties and 121 salt-tolerant rice varieties reported previously were then treated with 0.3% NaCl and 0.5% NaCl during entire growth period. Eleven plants from 7 varieties tolerant to 0.3% NaCl were obtained. One plants from one variety tolerant to 0.5% NaCl were obtained. These salt-tolerant varieties provided materials for the study on mechanism of salinity tolerance and cultivar innovation.
