CIMMYT bread wheat breeding lines

A total of 74,403 bread wheat breeding lines from the year 2013-2020 developed by the International Maize and Wheat Improvement Center (CIMMYT) was genotyped. We used genotyping-by-sequencing (GBS) to construct 433 GBS libraries which were sequenced in the Illumina platform to generate 440 FASTQ files. The key file consists of metadata such as sample name, flowcell, lane number, and barcode used for multiplexing samples. The FASTQ file of corresponding samples can be identified based on the library. The raw reads are available at National Center for Biotechnology Information (NCBI) with BioProject accession PRJNA498085.

本数据集涵盖国际玉米小麦改良中心（International Maize and Wheat Improvement Center, CIMMYT）于2013至2020年培育的74403份面包小麦（bread wheat）育种系，所有材料均已完成基因分型。研究采用测序分型技术（genotyping-by-sequencing, GBS）构建了433个GBS文库，随后在Illumina测序平台对上述文库进行测序，共生成440个FASTQ文件。关键元数据文件包含样本名称、流动池（flowcell）、泳道编号以及样本多重测序所用的条码（barcode）等信息，可通过文库信息匹配得到对应样本的FASTQ文件。原始测序读段（raw reads）已上传至美国国家生物技术信息中心（National Center for Biotechnology Information, NCBI），其生物项目登录号为PRJNA498085。
