Representation of QTL confidence intervals (peak LOD scores minus 1) on chromosomes 4, 5, and 8, with QTLs for carbon isotope discrimination (Δ13C) indicated by black rectangles and all others indicated by gray rectangles as follows: specific leaf area and percent nitrogen (SLA and %N), leaf width (LW), tiller number (TN), leaf curling and leaf drooping (LC and LD), photosynthesis rate and ratio of plant CO2 concentration/air CO2 concentration (A/m2 and Ci/Ca), stomatal conductance (SCO), and logarithm of leaf ABA concentration measured in medium vapor pressure deficit (lABA). Chromosome maps for the IR64 × Azucena doubled haploid (DH, on left) and recombinant inbred (RI, on right) populations were aligned based on common markers (indicated by connecting lines between pairs of maps).
