The physical and genetic positions of the 2‐LOD support intervals for each QTL are shown. LOD scores, additive effect, P‐value of additive effect, dominance effect, P‐value of dominance effect and percent variance explained (PVE) were calculated for each QTL. Positive additive effect (+) indicates that the teosinte allele increased the number of vascular bundles. Negative additive effect (−) indicates that the maize allele increased the number of vascular bundles.
