Received: DecemAccepted: Published: May 19, 2017 wrsggl1-1BS is potentially a novel stripe rust resistance gene that can be incorporated into modern breeding materials, along with other all-stage and adult-plant resistance genes to develop cultivars that can provide durable resistance.Ĭitation: Sthapit Kandel J, Krishnan V, Jiwan D, Chen X, Skinner DZ, See DR (2017) Mapping genes for resistance to stripe rust in spring wheat landrace PI 480035. Comparison with markers associated with previously reported Yr genes on 1B ( Yr64, Yr65, and YrH52) indicated that QYr. wrsggl1-3B, was identified on 3B, which was significant only for PSTv-40 and was not significant in the field, indicating it confers a race-specific resistance. wrsggl1-1BS, Xcfd59 0.59 cM proximal and XA365 3.19 cM proximal to QYr. The closest flanking markers were Xgwm273, Xgwm11, and Xbarc187 1.01 cM distal to QYr. wrsggl1-1BS was identified on chromosome 1B. The population was genotyped with genotyping-by-sequencing and microsatellite markers across the whole wheat genome. The population was evaluated in the field in 20 and seedling reactions were examined against three races (PSTv-14, PSTv-37, and PSTv-40) of the pathogen under controlled conditions. A spring wheat, “Avocet Susceptible” (AvS), was crossed with PI 480035 to develop a biparental population of 110 recombinant inbred lines (RIL). The objective of this research was to identify quantitative trait loci (QTL) for stripe rust resistance in PI 480035. Hexaploid spring wheat landrace PI 480035 was highly resistant to stripe rust in the field in Washington during 20. is an economically important disease of wheat ( Triticum aestivum L.).
