Abstract
A study was conducted on thirteen local lowland rice cultivars in Sarawak. In this study, all thirteen cultivars were treated with two levels of salinity treatments (1,000 and 10,000 ppm} and a control from germination to early seedling growth in pots. There were no significant differences in germination, and shoot and root length of seedlings at 8 days after incubation. Rice growth performance was affected by salt-stress. Seedling height was stunted. Seedling height assessment at 9 weeks after germination showed all rice cultivars, except ARC 2 were significantly reduced in height with 10,000 ppm salinity treatment compared to the control. Cultivars with less than 10% reduction in plant height with the 10,000 ppm salinity treatment were ARC 2, Adan Sederhana, Rotan, and Serendah Kuning, indicating significant salinity tolerance ability. Aceh 62, Bario Halus, Biris, Bario Sederhana, Kuduk, Lasak, and Ukong had moderate tolerance to salinity. Bario 2 and Suratani were the least tolerant cultivars.
