Genotyping analysis of over 130,000 CIMMYT bread wheat breeding lines: A decade-long effort in optimizing wheat genotyping

A total of 130,247 bread wheat breeding lines from the year 2013-2023 developed by the International Maize and Wheat Improvement Center (CIMMYT) were genotyped. We used genotyping-by-sequencing (GBS) to construct 636 GBS libraries and sequenced them in the Illumina platform to generate 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 the National Center for Biotechnology Information (NCBI) with BioProject accessions PRJNA498085 (2013 – 2020 data), PRJNA901877 (2021), PRJNA901925 and PRJNA901462 (2022) and PRJNA1044425 (2023).
