Fig. 4. Plot of QTL likelihood (LOD) over chromosome 3 for specific leaf area (SLA) in barley measured at 27 d after emergence (DAE) and for SLA corrected at the same developmental stage (DS) of 0.35, roughly equivalent to the time of 27 DAE (redrawn from Yin et al., 1999a). The horizontal line at a height of 2.5 indicates the threshold for the presence of a QTL. The dotted curve is from the use of the interval mapping method (Lander and Botstein, 1989), and the thin continuous one is from the use of the multiple-QTL mapping method (Jansen, 1995).
