摘要
Genotyping arrays based on single nucleotide polymorphisms(SNPs)provide a low-cost,highthroughput platform.The development of a SNP array that fully reflects the genetic diversity of maize(Zea mays L.)germplasm and is applicable to molecular breeding programs is desirable.In this study,we developed a MaizeGerm50K array comprising 50,852 SNPs selected from the resequencing data of 1604 maize inbred lines and other markers.A genome-wide association study using a landrace panel genotyped with the array permitted mapping of several known genes.We also verified a candidate gene,RNA-binding motif protein 24-like 1(ZmRBM24L1),delaying flowering through overexpression lines.Genomic selection for yield and agronomic traits showed high prediction accuracy.The MaizeGerm50K array is thus a valuable genomic tool for maize genetic studies and breeding.
