Bread Wheat With High Salinity and Sodicity Tolerance.

ABSTRACT: Soil salinity and sodicity are major constraints to global cereal production, but breeding for tolerance has been slow. Narrow gene pools, over-emphasis on the sodium (Na⁺) exclusion mechanism, little attention to osmotic stress/tissue tolerance mechanism(s) in which accumulation of inorganic ions such as Na⁺ is implicated, and lack of a suitable screening method have impaired progress. The aims of this study were to discover novel genes for Na⁺ accumulation using genome-wide association studies, compare growth responses to salinity and sodicity in low-Na⁺ bread Westonia with Nax1 and Nax2 genes and high-Na⁺ bread wheat Baart-46, and evaluate growth responses to salinity and sodicity in bread wheats with varying leaf Na
