N2  - Downy mildew (DM) epidemics have repeatedly caused huge grain and straw production losses
on pearl millet single-cross hybrids in India. 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.
