This study contains the re-sequencing data of 100 Lactuca accessions derived from the CGN (Centre for Genetic Resources, the Netherlands) collection.

The collection was developed within the framework of the TKI project, entitled ‘International Lactuca Genomics Consortium (ILGC)’ (Project number:1406-039) . For this project a cross section of the lettuce gene pool, comprising nearly 500 accessions from theCGN (Centre for Genetic Resources, the Netherlands) collection, was selected for DNA resequencing purposes. Resequencing of 100 lines was initiated in 2017 within the framework of the ILGC.
