TAILIEUCHUNG - Combined linkage and association mapping reveal QTL for host plant resistance to common rust (Puccinia sorghi) in tropical maize

Common rust, caused by Puccinia sorghi, is an important foliar disease of maize that has been associated with up to 50% grain yield loss. Development of resistant maize germplasm is the ideal strategy to combat P. sorghi. | Combined linkage and association mapping reveal QTL for host plant resistance to common rust Puccinia sorghi in tropical maize .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Zheng et al.

Development of resistant maize germplasm is the ideal strategy to lt br gt combat P. sorghi. lt br gt Results Association mapping performed using a mixed linear model MLM integrating population structure and lt br gt family relatedness identified 25 QTL P lt 10 5 that were associated with resistance to common rust and lt br gt distributed on chromosomes 1 3 5 6 8 and 10. We identified three QTLs associated with all three disease lt br gt parameters final disease rating mean disease rating and area under disease progress curve located on lt br gt chromosomes 1 3 and 8. A total of 5 QTLs for resistance to common rust were identified in the RIL population. lt br gt Nine candidate genes located on chromosomes 1 5 6 8 and 10 for resistance to common rust associated loci lt br gt were identified through detailed annotation. lt br gt Conclusions Using a diverse set of inbred lines genotyped with high density markers and evaluated for common lt br gt rust resistance in multiple environments it was .
