  Soil salinity is one of the major abiotic stresses affecting plant growth and crop production.In the present study, salt tolerance at rice seedling stage was evaluated using 87 introgression lines (ILs), which were derived from a cross between an elite indica cultivar Teqing and an accession of common wild rice (Oryza rufipogon Griff.).
