Screening and Adaptation in Some Varieties of Rice under Salinity Stress (Case Study at Paluh Merbau, Deli Serdang District, North Sumatera,Indonesia)

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 and rice production in this location is low. Aim of this research is to obtain tolerant variety with high adaptation under salinity stress. Research was conducted in Paluh Merbau village, Percut Sei Tuan, Deli Serdang District, North Sumatera, by using randomized block design non factorial with three replications. Response of growth and adaptation of 30 genotypes were tested and make classification based on criteria: highly susceptible, susceptible, moder ate, tolerant and highly tolerant by using a scoring method (salt injury score). Result of this research showed that IR 42 and Banyuasin had the best growth and highly adaptability on saline soil as compared with other genotypes.
