Fig. 4From: qMrdd2, a novel quantitative resistance locus for maize rough dwarf diseaseExperimental flow chart for QTL identification and fine-mapping of QTL qMrdd2, which confers resistance to MRDD. A total of 199 RILs were used for the initial QTL mapping. Recombinants identified within the F6-F9 populations were genotyped and investigated to fine-map the QTL qMrdd2Back to article page
