Association analysis between SNP markers and the three traits studied. Na+ and K+ concentration in third leaf, and K+/Na+ ratio were analysed in the F2 cross Jandaroi × AUS-14740. A LOD score of the association, the percentage of phenotypic trait variability and origin of the favourable allele were identified by marker regression analysis (MRA) in QTX MapManager
