The genetic mechanisms of the plant architecture related traits are analyzed in this paper by using the high-density genetic linkage map of the maize. This map is of great significance for breeding new maize varieties of ideal plant type. To develop high-throughput SNP markers for the high quality map from Chang 7-2×PHB1M, and the map QTL of the plant type related traits, 2 parents and 138 individuals of their F_2:3 population are detected by the SLAF-seq technology. The results are used to construct a highdensity genetic map with a total distance of 1354.81 cM, an average distance of 0.32 cM between markers, and with 4220 SLAF (7876 SNPS) as markers. With the densities of E1 and E2, QTL is mapped for the plant height, the ear height, the leaf count, the internode count and the average internode length. A total of 10 QTLs are detected, and the PVE of 7 QTLs exceeds 10%. The leaf count, the ear height and the internode number are the major QTLs and the ADD is negative. The decreasing effect alleles of the leaf count and the internode count are from PHB1M, and the ear height is from Chang 7-2. The leaf count and the internode count are located on the chromosome 8 at both densities, showing that they have a common genetic mechanism. There are a total of 61 SLAF markers associated with the QTL, among which SLFA7305498 and SLFA6717271 are the common markers of qLC- 2-LG8 and qIC-2-LG8. This study provides a support for the marker-assisted selection of the plant architecture traits., authors=XUE Chunlei^1,2, WU Hui³, LU Xiaoping¹, HAN Pingan², SUN Fengcheng², ZHANG Laihou², authorsList=XUE Chunlei, WU Hui, LU Xiaoping, HAN Pingan, SUN Fengcheng, ZHANG Laihou, authorCompany=1.
