    Area of Science:

    • Plant genetics
    • Quantitative trait genetics
    • Maize genetics

    Background:

    • Association studies are underutilized in plant genetics due to concerns about population structure.
    • Population structure can lead to false positives in genetic association analyses.
    • Controlling for population structure is crucial for accurate genetic discoveries.

    Discussion:

    • This study pioneers the application of structured association methods in plant genetics.
    • These statistical approaches leverage independent loci to correct for population structure and admixture.
    • This addresses a major limitation that has historically hindered the use of association studies in plants.
