We performed a genetic characterization of a semi-dwarf line (ND23049) that combines short stature, strong stiff culms, and adequate spike emergence. We developed a doubled haploid (DH) population derived by crossing ND23049 and the cultivar CLE253. A subset of 88 DH lines and parents were characterized for plant height in 2013 and 2014 and genotyped. In total, 1984 SNPs (345 unique loci) were used to produce a linkage map of 1127.1 cM. Three QTLs for plant height were detected in this population and coincided with the HvGA20ox2\/Sdw1, HvBRI1\/Uzu1, and HvPRR95 gene loci. The phenotypic variation explained by each QTL was 75.8%, 7.7%, and 4.1%, respectively, and jointly explained 83.3% (2013) and 87.7% (2014) of plant height. Our results suggest that ND23049 contributed the \u201cshort\u201d allele at the HvGA20ox2\/sdw1 locus while CLE253 provided \u201cshort\u201d alleles at the HvBRI1\/uzu1 and HvPRR95 loci. We identified a large deletion (at least 92.7 Kb), including HvGA20ox2 (Sdw1), as the causal mutation in ND23049. A set of tightly flanked SNP markers will help breeders to develop improved semi-dwarf varieties. <\/jats:p>","DOI":"10.1139\/gen-2017-0211","type":"journal-article","created":{"date-parts":[[2018,4,15]],"date-time":"2018-04-15T18:49:49Z","timestamp":1523818189000},"page":"429-436","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["QTL mapping uncovers a semi-dwarf 1 (<i>sdw1<\/i>) allele in the barley (<i>Hordeum vulgare<\/i>) ND23049 line"],"prefix":"10.1139","volume":"61","author":[{"given":"S\u00e9bastien","family":"B\u00e9langer","sequence":"first","affiliation":[{"name":"D\u00e9partement de phytologie and Institut de biologie int\u00e9grative et des syst\u00e8mes, Universit\u00e9 Laval, Quebec City, Quebec, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phanie","family":"Paquet-Marceau","sequence":"additional","affiliation":[{"name":"D\u00e9partement de phytologie and Institut de biologie int\u00e9grative et des syst\u00e8mes, Universit\u00e9 Laval, Quebec City, Quebec, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan E.","family":"D\u00edaz Lago","sequence":"additional","affiliation":[{"name":"PGG Wrightson Seeds, Montevideo, Uruguay."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fran\u00e7ois","family":"Belzile","sequence":"additional","affiliation":[{"name":"D\u00e9partement de phytologie and Institut de biologie int\u00e9grative et des syst\u00e8mes, Universit\u00e9 Laval, Quebec City, Quebec, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.3389\/fgene.2016.00117"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1038\/35035083"},{"key":"refg3\/ref3","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0003376"},{"key":"refg4\/ref4","doi-asserted-by":"publisher","DOI":"10.1139\/g93-143"},{"key":"refg5\/ref5","doi-asserted-by":"publisher","DOI":"10.1007\/s00122-016-2711-5"},{"key":"refg6\/ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s11032-015-0253-1"},{"key":"refg7\/ref7","doi-asserted-by":"publisher","DOI":"10.1104\/pp.103.026195"},{"key":"refg8\/ref8","doi-asserted-by":"publisher","DOI":"10.1093\/jxb\/eru521"},{"key":"refg9\/ref9","doi-asserted-by":"publisher","DOI":"10.1104\/pp.114.250738"},{"key":"refg10\/ref10","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0019379"},{"key":"refg11\/ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s00299-014-1583-x"},{"key":"refg12\/ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s00299-014-1563-1"},{"key":"refg13\/ref13","first-page":"36","volume":"42","author":"Franckowiak J.D.","year":"2012","journal-title":"Barley Genet.
