Description
Keyu Li and colleagues mapped genes for leaf angle in maize in 2026, a trait that shapes how much light dense plantings capture. Upright leaves let more light reach lower leaves, supporting high-density planting and higher yields. The genetic basis of leaf angle in southeast Chinese breeding lines was not fully mapped.
A panel of 212 inbred lines was genotyped with a 60,000-marker array, and five association models were run. Fourteen significant markers and 342 nearby candidate genes emerged, with six markers stable across models, including four novel loci. Eleven high-confidence genes at those loci point to hormone signaling and leaf development pathways. Breeders gain targets for shaping maize canopies for denser planting.
