Large amount of variability was noted for these traits and 45 plants with consistent superior growth characteristics were selected for further evaluation. Smooth cordgrass will tolerate regular inundations with 0 to 35 parts per thousand salinity. Smooth cordgrass (Spartina alterniflora) is used extensively for shoreline protection and tidal marsh restoration on the Atlantic and Gulf coasts because of its aggressive colonizing ability and tolerance to a wide range of salinity. DNA fingerprinting protocols developed through this project will help to test the authenticity of plant materials used in the restoration projects. Fourteen RAPD primers and 26 AFLP primer combinations generated a total of 201 and 2430 DNA fragments respectively.
