tolerance is essential to hasten the process of developing improved varieties with higher tolerance&#13;
through genomics-assisted breeding. In this context, an improved genetic map with 1205 loci was developed&#13;
spanning 2598.3cM with an average 2.2cM distance between loci in the recombinant inbred&#13;
line (TAG 24 � ICGV 86031) population using high-density 58K single nucleotide polymorphism&#13;
(SNP) “Axiom_Arachis” array. Quantitative trait locus (QTL) analysis was performed using extensive&#13;
phenotyping data generated for 20 drought tolerance- and two iron deficiency tolerance-related&#13;
traits from eight seasons (2004–2015) at two locations in India, one in Niger, and one in Senegal.&#13;
The genome-wide QTL discovery analysis identified 19 major main-effect QTLs with 10.0–33.9%&#13;
phenotypic variation explained (PVE) for drought tolerance- and iron deficiency tolerance- related&#13;
traits. Major main-effect QTLs were detected for haulm weight (20.1% PVE), SCMR (soil plant analytical&#13;
development (SPAD) chlorophyll meter reading, 22.4% PVE), and visual chlorosis rate (33.9%&#13;
PVE). Several important candidate genes encoding glycosyl hydrolases; malate dehydrogenases;&#13;
microtubule-associated proteins; and transcription factors such as MADS-box, basic helix-loop-helix&#13;
(bHLH), NAM, ATAF, and CUC (NAC), and myeloblastosis (MYB) were identified underlying these&#13;
QTL regions. The putative function of these genes indicated their possible involvement in plant&#13;
growth, development of seed and pod, and photosynthesis under drought or iron deficiency conditions&#13;
in groundnut. These genomic regions and candidate genes, after validation, may be useful&#13;
to develop molecular markers for deploying genomics-assisted breeding for enhancing groundnut&#13;
yield under drought stress and iron-deficient soil conditions.</mods:abstract><mods:classification authority="lcc">Abiotic Stress</mods:classification><mods:classification authority="lcc">Groundnut</mods:classification><mods:classification authority="lcc">Genetics and Genomics</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2020-12</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>MDPI</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
