Figure 1From: Identification and fine-mapping of a QTL, qMrdd1, that confers recessive resistance to maize rough dwarf diseaseExperimental flow chart for QTL identification and fine-mapping. Twenty-four HIFs were selected for trait-marker association analysis. Associated regions were validated using two BC1 populations, and a major QTL, qMrdd1, was identified and mapped. Recombinants identified within the BC1F4 population were genotyped and phenotyped to fine-map the QTL.Back to article page
