DNA was extracted from 21-day-old seedlings grown in a glasshouse at Rothamsted Research, UK, and genotyped using the commercially available TaNG v1.1 Affymetrix Axiom array at the Bristol Genomics Facility, University of Bristol. The genotypic data are provided in HapMap double-bit format. This work aimed to improve nitrogen use efficiency (NUE) in wheat as part of efforts toward sustainable yield enhancement and global food security. Genetic dissection of key agronomic traits presents a viable strategy for developing high-yielding, nitrogen-efficient wheat cultivars. The data support a genome-wide association study (GWAS) that related NUE traits to potential genetic markers. The research was funded by the Natural Environment Research Council (Grant NE/S009019/1)." ; dcterms:provenance [ a dcterms:ProvenanceStatement ; rdfs:label "DNA was extracted from 21 day old seedlings using the Wizard Genomic DNA Purification Kit (Promega, UK). Quantity and quality was checked using an ND-1000 spectrophotometer (Thermo Fisher Scientific, USA) and a Qubit 2.0 fluorometer using a Qubit dsDNA quantification kit (Invitrogen, UK). The quality thresholds were as follows: an OD260/OD280 ratio of between 1.8 and 2.0 and a OD260/OD230 ratio greater than 1.5. High-throughput SNP genotyping of 323 genotypes was performed using the TaNG v1.1 Affymetrix Axiom genotyping array (Thermo Fisher Scientific, UK) at the University of Bristol Genomics facility, University of Bristol, UK. Genotype calling was performed using the Best Practices Workflow in the Axiom Analysis Suite (AxAS) following the default SNP quality control thresholds where DCQ (dish quality control) ≥ 0.82 and CR (call rate) cut-off ≥ 97%. Markers were then classified and filtered based on the Axiom recommended criteria. Subsequently, markers that were monomorphic, had a minor allele frequency (MAF) of <5%, a missing call rate of >20%, or a heterozygote frequency >25% were removed. After filtering, a total of 6,315 best recommended and high-quality markers were retained and were used to generate the HapMap-formatted data." ] ; dcterms:spatial [ a dcterms:Location ; dcat:bbox "POLYGON((-0.382 51.804, -0.382 51.815, -0.359 51.815, -0.359 51.804, -0.382 51.804))"^^geo:wktLiteral ; ] ; dcat:contactPoint :c0 ; dcterms:publisher ; dcterms:subject , , "nitrogen use efficiency", "Pakistan" ; prov:wasGeneratedBy ; a dcat:Dataset; dcterms:type dcmitype:Dataset ; dcterms:available "2025-11-26"^^xsd:date ; dcat:landingPage , ; dcterms:license ; dcterms:accessRights ; dcterms:theme ; dcterms:creator :a0, :a1, :a2, :a3, :a4, :a5, :a6, :a7, :a8, :a9, :a10, :a11, :a12, :a13 ; dcterms:language . :c0 a foaf:Person ; foaf:name "Prins, A." ; foaf:familyName "Prins" ; foaf:givenName "A." ; vcard:hasEmail "anneke.prins@rothamsted.ac.uk" ; foaf:member ; . a foaf:Organization ; foaf:name "NERC EDS Environmental Information Data Centre" ; vcard:hasEmail "info@eidc.ac.uk" ; foaf:member ; . :a0 a foaf:Person ; foaf:name "Iqbal, R." ; foaf:familyName "Iqbal" ; foaf:givenName "Rubab" ; vcard:hasEmail "rubabiqbalphd@gmail.com" ; foaf:member ; . :a1 a foaf:Person ; foaf:name "Bano, Z." ; foaf:familyName "Bano" ; foaf:givenName "Zunaira" ; vcard:hasEmail "banozunaira7@gmail.com" ; foaf:member ; . :a2 a foaf:Person ; foaf:name "Kiran, A." ; foaf:familyName "Kiran" ; foaf:givenName "Aysha" ; vcard:hasEmail "aysha.kiran@uaf.edu.pk" ; foaf:member ; . :a3 a foaf:Person ; foaf:name "Naeem, M.K." ; foaf:familyName "Naeem" ; foaf:givenName "Muhammad Kashif" ; vcard:hasEmail "kashifuaar102@hotmail.com" ; foaf:member [foaf:name "National Agricultural Research Center Islamabad"] ; . :a4 a foaf:Person ; foaf:name "Khan, M.R." ; foaf:familyName "Khan" ; foaf:givenName "Muhammad Ramzan" ; vcard:hasEmail "mrkhan@parc.gov.pk" ; foaf:member [foaf:name "National Agricultural Research Center Islamabad"] ; . :a5 a foaf:Person ; foaf:name "Wakeel, A." ; foaf:familyName "Wakeel" ; foaf:givenName "Abdul" ; vcard:hasEmail "abdulwakeel77@gmail.com" ; foaf:member ; . :a6 a foaf:Person ; foaf:name "Sajjad, H." ; foaf:familyName "Sajjad" ; foaf:givenName "Hassan" ; vcard:hasEmail "aysha.kiran@uaf.edu.pk" ; foaf:member ; . :a7 a foaf:Person ; foaf:name "Aziz, T." ; foaf:familyName "Aziz" ; foaf:givenName "Tariq" ; vcard:hasEmail "draziz@uaf.edu.pk" ; foaf:member ; . :a8 a foaf:Person ; foaf:name "Sutton, M." ; foaf:familyName "Sutton" ; foaf:givenName "Mark" ; vcard:hasEmail "enquiries@ceh.ac.uk" ; foaf:member ; . :a9 a foaf:Person ; foaf:name "Price, A." ; foaf:familyName "Price" ; foaf:givenName "Adam" ; vcard:hasEmail "a.price@abdn.ac.uk" ; foaf:member ; . :a10 a foaf:Person ; foaf:name "Prins, A." ; foaf:familyName "Prins" ; foaf:givenName "Anneke" ; vcard:hasEmail "anneke.prins@rothamsted.ac.uk" ; foaf:member ; . :a11 a foaf:Person ; foaf:name "Shewry, P." ; foaf:familyName "Shewry" ; foaf:givenName "Peter" ; vcard:hasEmail "peter.shewry@rothamsted.ac.uk" ; foaf:member ; . :a12 a foaf:Person ; foaf:name "Alabdullah, A.K." ; foaf:familyName "Alabdullah" ; foaf:givenName "Abdul Kader" ; vcard:hasEmail "Abdul-Kader.Alabdullah@jic.ac.uk" ; foaf:member ; . :a13 a foaf:Person ; foaf:name "Maqsood, M.A." ; foaf:familyName "Maqsood" ; foaf:givenName "Muhammad Aamer" ; vcard:hasEmail "mohamgill@uaf.edu.pk" ; foaf:member [foaf:name "National Agricultural Research Center Islamabad"] ; . a skos:Concept; skos:prefLabel "Agriculture"; rdfs:label "Agriculture" . a skos:Concept; skos:prefLabel "nitrogenous fertiliser"; rdfs:label "nitrogenous fertiliser" . a foaf:Organization ; foaf:name "Rothamsted Research" . a foaf:Organization ; foaf:name "University of Agriculture Faisalabad" . a foaf:Organization ; foaf:name "UK Centre for Ecology & Hydrology" . a foaf:Organization ; foaf:name "University of Aberdeen" . a foaf:Organization ; foaf:name "John Innes Centre" . a prov:Activity ; rdfs:label "GCRF South Asian Nitrogen Hub" .
