Plant height is one of the most important agronomic traits in maize (Zea mays L.), related to morphology, lodging and yield. To realize more clearly its genetic basis, in this study, the quantitative trait loci (QTLs) for plant height were identified using a recombinant inbred line (RIL) population consisting of 239 RILs derived from the cross between the two maize inbred lines Mo17 and Huangzao4. As a result, three QTLs were mapped on chromosomes 1, 6 and 9. The QTL on chromosome 1 has a mapping interval of 5 cM near to its adjacent markers, could explain 17.94% of phenotypic variation, due to additive effect, it could make plant height increase 9.67 cm. The two QTLs on chromosomes 6 and 9 were quite near to their adjacent markers, with a mapping interval of 0 cM, they could severally account for 41.98 and 4.89% of phenotypic variation; owing to additive effects, they could decrease plant height 2.66 and 5.04 cm, respectively. According to the phenotypic values of parental lines and the additive-effect values of the three QTLs, it was concluded that the QTL on chromosome 1 was from Mo 17, while the other two were from Huanzao4.
