Genotyping-by-sequencing data of wheat lines grown in 2017 preliminary yield trials in the Nebraska small grains breeding program

This study comprises genotyping-by-sequencing data of 273 wheat (Triticum aestivum) lines grown in 2017 preliminary yield trials (F3:6) in the Nebraska small grains breeding program. The DNA was extracted from the F3:5 lines grown in 2016 and the same marker data was used for the F3:6 lines grown in 2017. SNPs called from this data were used in genome-wide association studies and genomic selection.本研究包含273份普通小麦（Triticum aestivum）株系的测序基因分型（genotyping-by-sequencing，GBS）数据，相关株系参与了2017年内布拉斯加小谷物育种项目的F3:6代预备产量试验。本研究的DNA样本提取自2016年种植的F3:5株系，而2017年种植的F3:6株系则采用了同一套分子标记数据。从该测序分型数据中鉴定得到的单核苷酸多态性（Single Nucleotide Polymorphism，SNP，复数形式为SNPs）位点，被用于全基因组关联研究（genome-wide association study，GWAS）与基因组选择（genomic selection，GS）。
