Spike length(SL), grain number per spike(GNS), and grain weight per spike(GWS) are important spike traits associated with yield in wheat. In this study, quantitative trait loci(QTLs) for spike traits were mapped using an available high-density SNP and SSR genetic linkage map developed from a recombinant inbred line(RIL) population of Yanda 1817 × Beinong 6. Using phenotypic data on two locations(Beijing and Shijiazhuang) in two years(2011–2012 and 2012–2013 growing seasons), 29 QTLs for SL, GNS and GWS were...
