Figure 5. Individual and combined QTL for root and shoot traits within a treatment, shown as colorful bars, with thickness indicating confidence interval, and position indicating location along the chromosome (A1-A10, C1-C9).

Red = ‘normal’ Pi (NP, 0.25 mM Pi) and blue = low Pi (LP, 0 mM Pi) in the hydroponic ‘pouch and wick’ system (P), yellow = high Pi (HP, 0.625 mM Pi) and black = low P (LP, 0 mM Pi) in the agar screening system (A). LRD = lateral root density, LRN = lateral root number, MLRL = mean lateral root length, PRL = primary root length, TLRL = total lateral root length, TRL = total root length, SDW = shoot dry weight, RDW = root dry weight, TDW = total dry weight. DW means QTL for SDW, RDW and TDW. QTLs were detected using the new TNDH 2041-map.
