Genome-Wide Association Study of Complex Traits in Maize Detects Genomic Regions and Genes for Increasing Grain Yield and Grain Quality

This review describes the current status of genome-wide association study (GWAS) major crops in maize (Zea mays L.) concentrate on performing mapping as a novel method associating genetic and complex traits, strategy analyzing phenotype genotype data to identify population structure linkage disequilibrium. GWAS has an important role food security because this identified many crucial genomic regions traits most commercialize world, such maize. These including yield, grain quality, biofortification, biotic abiotic resistance. advantages correlated with reducing genotyping cost research time, increasing resolution larger allele number. Meanwhile, two main limitations related size number markers. There are software packages for analysis GWAS. The commonly that was used especially crop is TASSEL frequently updated. Recently, papers concentrated accelerated identification regions, candidate genes within these their metabolomic yield quality fulfill market demands.
