Table 4 ANOVA, genetic variance (GV) and broad sense heritability (H2) for P use efficiency related traits recorded in three subpopulations (C1, C2 and C3), obtained from 82 bread wheat accessions, grown under sufficient (500 µM) and low (5 µM) concentration in hydroponics. Abbreviations: TBM, total biomass; SDW, shoot dry weight; RDW, root dry weight; RSR, root-to-shoot ratio; PCON, phosphorus concentration; TPU, total phosphorus uptake. *P < .05; ** P < .01, *** P < .001; P – phosphorus; G – accession; PXG – interaction between P and G.
