Rice growth and development are adversely affected by salinity; it was a major environmental stress that limits agricultural production. “Paluh Merbau” is a village in “percut Sei Tuan District that had saline soil, It has EC = 6,8 mmhos. Aim of this research is to get the best variety in growth and adaptability under salinity stress. Research was undertaken in Paluh Merbau village, Percut Sei Tuan Sub-District, Deli Serdang District, North Sumatera, Indonesia) by using randomized block design non factorial with three replications. Response of growth and adaptation were tested of 10 genotype respectively were observed and classified by the criteria: sensitive, moderate, tolerant and very tolerant by using a scoring method (salt injury score). Observation of growth and adaptability showed that genotype IR 42 (in 2012 had the best growth and adaptability as compared with other genotype.
