  1. Phosphate sufficient (+Pi) and phosphate deficient (−Pi) treatments. DW = rosette dry weight, PHO = leaf Pi concentration, PUE = phosphate use efficiency, and SUL = leaf sulphate concentration. –log10(P) indicates the significance level, a threshold of –log10(P) = 2.9 is used for identification of significant QTLs, QTLxE indicates the presence or absence of QTL by environment interaction, R2 is the percentage of total phenotypic variance explained by each QTL. Effects with positive values represent a positive contribution of the Col allele to the trait value and those with negative values represent a positive contribution of the Sha allele to the trait value
