Measurements are on a per pot basis, with each pot consisting of two plants. Overall trait means, minimum and maximum values, and p-values for effects of genotype (G), treatment (T), and genotype by treatment interaction (G × T) are given for Genesis836, Rupali and a RIL population consisting of 200 genotypes. n.a is indicated for non-informative p-values where G × T was significant. Estimates of heritability (H²) for different traits under salt and control conditions is indicated.
