Three methods were employed to test the resistance of rice varieties to salt in order to find a suitable way to screen the rice varieties or lines which were used in rice breeding progrom for salt resistant.
1. Five different treatments, 0.1, 0.2, 0.3, 0.4, and 0.5% of salt compared to total dry weight of soil, were employed to investigate the resistance of rice to salt. The injury of salt to rice plant was increased, when higher degree of salt was added. It was found that 0.3% salt treatment could be used in the screening program.
2. The result indicated that irrigated rice seedlings with salt solution was best and most convenience and large number of rice plant could be test. The results of three methods, however, showed almost same.
3. The resistant of ability of rice plant to salt was increased, when crop grow older. The best stage to test their resistance was at 4-leaf stage of rice seedling.
4. The most resistant rice variety was Hasawi according to this investigation.
