Analyses of parental lines and progeny in two F2 segregating populations. Concentration of third leaf Na+ and third leaf K+, and K+/Na+ ratio in F2 populations and parental forms (Jandaroi, AUS-14740 and AUS-14752) were measured and heritability values (h 2) were calculated after 10 d of salt stress (100 mM NaCl)
