Unlocking Maize Hybrid Vigor: Genetic and Molecular Insights
Received Date: May 01, 2025 / Published Date: May 29, 2025
Abstract
Maize hybrid vigor, or heterosis, is a vital trait for increasing crop yields. This review synthesizes recent research exploring the genetic and epigenetic underpinnings of heterosis in maize. Studies highlight the roles of overdominance, epistasis, gene regulatory networks, and epigenetic modifications. Advances in genomics and machine learning are improving the prediction and exploitation of hybrid vigor. The influence of population structure, hybridization strategies, root architecture, and stress tolerance on heterosis are also discussed, providing a comprehensive outlook for future breeding advancements.
