In total, 207 wheat genotypes (111 spring and 96 winter type) were analysed using a 15k Infinium SNP array, which is an optimized and reduced version of the
90k iSELECT SNP-chip described by Wang et al. (2014) Plant Biotechnol J 12:787-796. The development of the 15k SNP-chip and genotyping was performed by TraitGenetics GmbH
(http://www.traitgenetics.com).
