Abstract: To investigate the salt tolerance of several different rice strains and provide good germplasm resources for salt-tolerant breeding, 7 rice varieties were used in the study. With different NaCl concentrations (0, 0.125, 0.15, 0.2 mol/L), the germinating energy, germinative percentage, root length, shoot length, fresh weight of shoot and main root number were measured and then were analyzed with multivariate analysis method. The results showed that all the testing indexes of different rice varieties decreased with varied degrees. Under salt stress of 0.15 mol/L concentration, ‘S83’ and ‘S85’ showed certain tolerance and ‘S88’ showed a relatively strong tolerance. The results of multivariate analysis indicated that ‘S88’ had stronger salt tolerance.
