: the same association marker detected by different approach;
: year, i.e., 2009, and 2010; SA: salt; AL: alkaline.
: marker in similar result column is linked to the associated marker in this study; M: main-effect QTL; Y: year; T: treatment. LR: Length of main root; FWR: Fresh weight of root; DWR: Dried weight of root; LH; Length of hypocotyl; BS: Biomass.
