Abstract
The present invention relates to markers of a Nax locus of wheat plants, particularly durum wheat, linked to reduced sodium accumulation, as well as enhanced tolerance to saline and/or sodic soils. The present invention also relates to the use of these markers in breeding programs to produce plants with reduced sodium accumulation, as well as enhanced tolerance to saline and/or sodic soils. Furthermore, the invention relates to plants produced by these breeding programs.
Claims30
A method of identifying a wheat plant having a phenotype of enhanced tolerance to saline and/or sodic soils, and/or reduced sodium accumulation in an aerial part of the plant, the method comprising detecting a nucleic acid molecule of the plant, wherein the nucleic acid molecule is linked to a Nax1 locus of wheat that comprises an allele that confers on the plant the phenotype of enhanced tolerance to saline and/or sodic soils and/or reduced sodium accumulation in an aerial part of the plant.
