Rapid QTL mapping strategy of plant height in maize. a The F₂ population was constructed with two inbred lines 52220 (short) and Mo18W (tall). Scale bar, 20 cm. b Rapid QTL mapping strategy of plant height: initial QTL mapping was performed in the F_2:3 population with a high-density genetic map of SNPs from GBS, and then QTL fine-mapping was conducted in the F_3:4 population. c High-density genetic map constructed from the F₂ population with 281 individuals using GBS (Color figure online)
