This study explored the core principles, creation methods and on-site implementation of the male sterility mechanism in wheat, especially the examination of light/temperature-sensitive genetic sterility (TPSGMS) and cell-based sterility (CMS) models, which are important components of the hybrid breeding program and can achieve effective cross-pollination management and improve the utilization of hybrid vitality. Modern techniques such as gene editing technology (CRISPR/Cas9) and rapid purebred breeding (DH breeding) have been employed to rapidly track the cultivation of stable sterile lines with the best growth characteristics. The success of hybrid wheat models demonstrates significant advancements in crop productivity, pathogen defense, and climate tolerance. This study assesses the current limitations in terms of wide implementation, consistency of climate-related performance, and acceptance by agricultural communities, and puts forward some targeted suggestions. This study analyzed and resolved the key challenges in the development of hybrid wheat, supporting the development of global food stability and eco-friendly agriculture.
