Salinity tolerance during seed germination from naturalized populations of tall wheatgrass

The phenotypic variability among ten adapted populations of tall wheatgrass (Thinopyrum ponticum) germinating under saline stress conditions was evaluated as part of a breeding program. The aim of the breeding program was to provide new cultivars of tall wheatgrass adapted to saline soil conditions. Saline soils represent 8% of the total agricultural soil surface in Argentina.
