Most QTL intervals identified with the platform overlapped with QTLs or causal genes reported previously for related phenotypes (Hart et al., 2001; Feltus et al., 2006; Mace and Jordan, 2011; Morris et al., 2013; Higgins et al., 2014). Dw3 was cloned previously (Multani et al., 2003). For image-based QTL intervals, the LOD-2 interval and peak coordinate for the phenotype with the maximum MLOD are reported, and the phenotype name is indicated by an asterisk; maximum MLOD coordinates are not applicable to intervals from the literature, indicated by a dash. Supplemental Table S1 contains all identified organ-level QTLs. Leaf pitch and leaf curve are both measures of Euclidean distance from the leaf base to the apex of the curved leaf blade and from the leaf base to the leaf tip, respectively (Feltus et al., 2006).
