Genetic separability of tolerance mechanisms. Further evidence that different lines may have different genes conferring tolerance. SES scores of an F₂ population derived from the cross of the two tolerant genotypes FL478 × Hasawi were recorded after treatment with 150 mM NaCl (applied at 21 days after germination). The F₂ population displayed transgressive segregation in both the sensitive (early timepoint, 14 days after salinisation, das; A) and tolerant (late timepoint, 34 days after salinisation; B) directions, compared with FL478 and Hasawi controls. IR29 (sensitive) is included for comparison.
