The Manhattan plot for length of main root (LR) using IIIVmrMLM software. A-B: QTNs for LR in 2014 and 2015 using single environment analysis of IIIVmrMLM. C: QTNs for LR using multi-environment joint analysis of IIIVmrMLM. D: QTN-by-environment interactions (QEIs) for LR using multi-environment joint analysis of IIIVmrMLM. E–F: QEIs for LR between control and salt treatments using multi-environment joint analysis of IIIVmrMLM. The black (one) and blue (multiple) lines indicate the times that the QTN/QEI was identified. The known and candidate genes were marked with red and black colors, respectively
