Meta-analysis of QTL for Fusarium head blight resistance in Chinese wheat landraces

In this study, we used maps of single nucleotide polymorphisms (SNP) developed from the five populations and identified 31 QTL on 16 chromosomes; 10 QTL were new. We constructed a consensus map and identified six meta-QTL (MQTL) and SNP within the MQTL regions using meta-analysis. Two of the MQTL were on chromosome 3BS (3BSd and 3BSc), and one on each of chromosomes 3A, 2D, 3D, and 4D. Twenty-two SNP closely linked to MQTL were converted into breeder friendly Kompetitive Allele Specific Polymerase Chain Reaction (KASP) assays, which should be useful for marker-assisted selection in breeding programs.
