Identification and characterization of stripe rust, leaf rust, leaf spot, and common bunt resistance in spring wheat

Hundreds of quantitative trait locus (QTL) have been reported in diverse types hexaploid wheat (Triticum aestivum L.) populations but direct comparisons QTLs different studies and are still challenging due to the lack physical positions for most QTLs. Here, we used International Wheat Genome Sequencing Consortium (IWGSC) RefSeq v2.0 map all markers associated with leaf spot (Ls), rust (Lr), stripe (Yr), common bunt (Cbt) resistance two recombinant inbred lines (RIL) populations. QTL mapping was conducted using IWGSC 3,158 5,732 markers, disease severity data Peace/Carberry Attila/CDC Go evaluated 3–8 environments. We uncovered a total 82 Yr (36), Ls (18), Lr (15), Cbt (13) individual overall means Among them, 29 were combined environments, which accounted 0.5-20.9% individually 12.4–41.2% per trait. Three (QLr.dms-2D.2, QLs.dms-5B, QYr.dms-5B.2) both Fourteen out stable as they identified Ten chromosome arms harbored cluster 2–4 diseases. This methodology would serve one resources compare based on improved information instead population-specific consensus linkage maps. article is protected by copyright. All rights reserved
