Abstract excerpt

KEY MESSAGE: Integration of multienvironment QTL mapping and GWAS revealed three candidate genes-ZmFum1, ZmDGAT1-1, and ZmLPAAT4-as potential key regulators of maize kernel oil content. With an exceptional energy density and high polyunsaturated fatty acid content, maize oil positions high-oil maize as multifunctional feedstocks. Exploring the genetic architecture of oil content (OC) in maize kernel is crucial...
