Salinity stress is an important cause of crop yield loss in many parts of the world. Here, we
performed genome‐wide association studies of salinity‐stress responsive traits in 132
HapMap genotypes of the model legume Medicago truncatula. Plants grown in soil were
subjected to a step‐wise increase in NaCl concentration, from 0 through 0.5% and 1.0% to
1.5%, and the following traits were measured: vigor, shoot biomass, shoot water content, leaf
chlorophyll content, leaf size, and leaf and root concentrations of proline and major ions …
