Maize (Zea mays L.) kernel width is one of the most important traits that related to yield and appearance. To understand its genetic mechanisms more clearly, a recombinant inbred line (RIL) segregation population consisting 239 RILs was used for quantitative trait locus (QTL) mapping width. We found four QTLs on chromosomes 3 (one), 5 (two), 10 (one). The were close their adjacent markers, with range 0-23.8 cM, explained 6.2-19.7% phenotypic variation. three had positive additive effects, certain extent increased width, whereas chromosome exhibited negative effects decreased These results can be gene cloning marker-assisted selection in maize-breeding programs.
