  1. DW = total rosette dry weight, PHO = leaf Pi concentration, PUE = phosphate use efficiency determined as shoot dry weight / PHO, and SUL = leaf sulphate concentration. Min and Max indicate the lowest and highest values; mean and standard deviation (Std) is indicated for all lines; H2 indicates broad sense heritability. In the ANOVA table, G, T, and GxT, refer to respectively genotype, treatment and genotype x treatment interaction and each of them is considered significant when the P value is ≤0.05
