        <dc:description>Background: Restoration of fertility (Rf) is an important trait for pigeonpea hybrid breeding. Few coarse&#13;
quantitative trait locus (QTL) studies conducted in the past identified QTLs with large confidence intervals on the&#13;
genetic map and could not provide any information on possible genes responsible for Rf in pigeonpea. Therefore, a&#13;
larger population comprising of 369 F2s derived from ICPA 2039 × ICPL 87119 was genotyped with high density&#13;
Axiom Cajanus SNP Array with 56 K single nucleotide polymorphism (SNPs) for high resolution mapping of Rf.&#13;
&#13;
Results: A genetic map with 4867 markers was developed and a total of four QTLs for Rf were identified. While one&#13;
major effect QTL (qRf8.1) was co-localized with the QTL identified in two previous studies and its size was refined&#13;
from 1.2 Mb to 0.41 Mb. Further analysis of qRf8.1 QTL with genome sequence provided 20 genes including two&#13;
genes namely flowering locus protein T and 2-oxoglutarate/Fe (II)-dependent dioxygenases (2-ODDs) superfamily&#13;
protein with known function in the restoration of fertility.&#13;
&#13;
Conclusion: The qRf8.1 QTL and the potential candidate genes present in this QTL will be valuable for genomicsassisted&#13;
breeding and identification of causal genes/nucleotides for the restoration of fertility in the hybrid&#13;
breeding program of pigeonpea.</dc:description>
