The ability to cope with high internal Na+ levels
was identified in a number of tetraploid landraces.
Five landraces from various T. turgidum subspecies
maintained a high percentage of green healthy leaves
despite having high levels of Na+, indicating that they
may have the ability to tolerate high internal Na+ at
the tissue or cellular level. These data suggest that
we have found genetic material with the potential to
improve the internal Na+ tolerance of durum cultivars
and even of bread wheat.
