ERS7400483 - Zea mays leaf samples of a magic population orginating from a funnel cross of 16 founder lines (B96, EP1, DK105, FV2, CO255, F492, A654, FV252, DK63, C103, OH43, A632, B73, W117, ND245, VA85) - The maize MAGIC panel used to perform association studies, was created from a funnel cross of 16 founder lines (B96, EP1, DK105, FV2, CO255, F492, A654, FV252, DK63, C103, OH43, A632, B73, W117, ND245, VA85) representing the most significant heterotic groups used for maize hybrid production in temperate regions (similar to the panel produced by Dell’Acqua et al. 45). The original population called BALANCE was used to extract 375 DHIL at the 3rd generation of mixing (G8). The crossing scheme used to create the MAGIC panel is illustrated in Extended data Fig. 4. The 375 DHILs along with the 16 founder lines and the tester were genotyped with the Axiom maize 600K array46. The parental origin of each allele in the DHILs was inferred using the R/qtl package47 and each DHIL was represented as a mosaic of the founder genomes, thus allowing in silico genotyping. The MAGIC panel allowed to detect more than 12 million Single Nucleotide Polymorphisms (SNPs) following Next Generation Sequencing (NGS) data of the 16 founders and of the tester line. Among these 12 million SNPs, approximately 8 million were selected using different criteria of quality control recommended by the US HapMap (Bukowski et al 2017) including Identification by Descent (IBD) and Linkage Disequilibrium (LD). These selected markers were positioned on the maize reference genome B73 RefGen_v4 | seqout
