Single-trait multiple-interval mapping of the QTL for pericarp thickness on ten chromosomes across three years in the BC4F3 population. Curves in the plot indicate the genetic coordinates along chromosomes within a chromosome (x-axis) and LOD score (y-axis) of the detected QTL. The mapping curve of the QTL that controls pericarp thickness is located on chromosome 10, and a common qPT10–5 was detected across three years. The dashed line indicates the significance threshold (LOD = 2.0)
