Pericarp thickness is of great importance to the sensory quality of sweet corn. Mining the gene for pericarp thickness and understanding its genetic mechanism can provide a base for instructing breeding. Quantitative trait locus(QTL) for pericarp thickness was detected based on two genetic models using a population comprising 190 BC1F2 families derived from the cross of Richao-1(thin pericarp, 56.57 μm) ×1021(thick pericarp, 100.23 μm) in the present study. Three QTLs for pericarp thickness were identified ...
