Abstract excerpt

Grain traits, including kernel dimensions and weight, are key determinants of maize yield and quality. To dissect their genetic basis, we evaluated kernel length, width, thickness, 100‑kernel weight, and volume in 187 maize accessions across two years, revealing significant trait correlations consistent with shared genetic regulation. Genome‑wide association studies identified 284 stable loci associated with...
