Fine-mapping of major QTL of plant height on maize chromosome 1. a The density of plant height distribution in the F2 population. b QTL mapping identified a major QTL of plant height in the position from 80 to 110 cM on maize chromosome 1; red dashed line signifies the significant threshold (P < 0.05) with 1000 permutations. c Fine-mapping of this major QTL of plant height in an F3:4 population with 5215 individuals. Marker tests were performed in the F3:4 population to test the correlation of plant height and molecular markers. Dark blue, light blue and white bars represent the genomic fragments of homozygous 52220 and heterozygous and homozygous Mo18W genotypes, respectively. The recombination break point was set in the middle of two flanking markers in each zygote. The arrows represent the molecular markers for fine mapping (Color figure online)
