The present study was undertaken to identify the QTL positions controlling DMR on the linkage map for a pearl millet mapping population of 295 F7 RIL population derived from a single F1 plant from plant × plant cross 81 B-P13 (susceptible) × AIMP 92901-P03 (resistant) using three isolates of the pathogen from Gujarat, Haryana and Rajasthan. A skeleton genetic linkage map of 536.8 cM (Haldane) was constructed using MapMaker/Exp version 3.0b at LOD threshold value of 3.0 using 39 scorable polymorphic loci. A total of four major DMR QTLs were identified on linkage groups of 1,3 and 4. The inheritance of of these QTLs showed AIMP 92901-P03 providing the resistant alleles. At least one DMR QTL was detected and mapped for each of the three DM isolates. After validation, marker-assisted selection (MAS) can now be used for improving DMR of elite pearl millet hybrid parental lines using polymorphic flanking markers from donor parent AIMP 92901-P03. publisher: Vital Biotech, India date: 2017 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/10458/1/Mapping%20Host%20Plant%20Resistance%20Qtls.pdf identifier: Saritha, A and Srivastava, R K and Reddy, N and Katiyar, P and Dangi, K S (2017) Mapping Host Plant Resistance Qtls against Three Virulent Isolates of Downy Mildew PathogenIn Pearl Millet (Pennisetum glaucum [L.] R.
