- Breeding ideotype maize for high-density planting is crucial for increasing yield.
- Homozygous favorable alleles in genes regulating four principal shoot traits play a prominent role in maize ideotype.
- Eight architecture-regulating genes were identified and functionally validated.
- Elite hybrid Yufeng303 was used as a chassis to develop five improved parental lines by pyramiding favorable alleles.
- Four new hybrids were created, achieving 4.1-9.2% higher plot yields than Yufeng303 across eight environments.
- This study exemplifies genomics-guided breeding of ideotype maize for high densities and serves as a template for other crops.
