Story summary
  • The study analyzes 108 maize hybrids and 447 inbred lines evaluated in Langfang, China, from 2017 to 2019, collecting phenotypes, allele profiles, and significant single nucleotide polymorphisms (SNPs).
  • It identifies quantitative trait loci (QTLs) for leaf angles and compares significant genome-wide association study peaks with prior studies.
  • It provides estimates of general and specific combining ability for yield from hybrid crosses involving multiple maternal and paternal families, guiding hybrid development.
