Genotyping of the Chinese Spring x Renan mapping population with the TaBW280K SNP array

The TaBW280K SNP array (Rimbert et al., PLoS ONE 2018) was used to genotype 430 Single Seed Descent (SSD) individuals derived from a cross between Chinese Spring and Renan (CsRe; Choulet et al., Science 2014). Out of the 280,226 probesets, 85,276 were found to be polymorphic between the two parental lines and PHR on the population. Eventually, 83,721 (98.2%) SNPs were genetically mapped in 21 linkage groups corresponding to the 21 chromosomes of bread wheat, with no unlinked markers. This file contains the genotyping data of the 430 SSD lines.

本研究采用TaBW280K单核苷酸多态性（Single Nucleotide Polymorphism, SNP）芯片（Rimbert等，《PLoS ONE》，2018），对由中国春（Chinese Spring）与雷南（Renan）杂交得到的430份单粒传（Single Seed Descent, SSD）后代个体（组合代号CsRe；Choulet等，《Science》，2014）开展基因分型。在280226个探针组中，共有85276个在两个亲本株系及群体内的PHR材料间呈现多态性。最终，83721个（占比98.2%）SNP被成功遗传定位至对应普通小麦21条染色体的21个连锁群中，无未连锁标记。本文件包含该430份SSD株系的基因分型数据。
