Tolerance is not well correlated with cultivar-groups. Tolerance is not well correlated with cultivar-groups in O. sativa, though few japonica accessions score tolerant overall, and few aromatic accessions score sensitive. Members of the aus cultivar-group generally score moderate to highly tolerant; indica accessions show a wide variability. Few accessions of O. glaberrima have been screened, but these seem to show as wide a range of tolerance and Na+ exclusion as seen in O. sativa.
