Abstract

Wheat hybrid breeding is a key approach to improving global wheat productivity and ensuring food security. However, reproductive barriers between different wheat species, difficulties in chromosome pairing, and sterility issues in hybrid seed production have limited the widespread adoption of hybrid wheat varieties. To overcome these biological barriers, scientists have developed various advanced technologies and methods, facilitating progress in wheat hybrid breeding. This study reviews the latest technological advancements in overcoming biological barriers in wheat hybrid breeding, focusing on the application of male sterility systems, embryo rescue techniques, and gene editing. It also analyzes the progress in genomic and molecular tools. The research finds that male sterility systems, embryo rescue techniques, and gene editing technologies have successfully addressed some of the biological barriers in wheat hybrid breeding. Successful cases of hybrid wheat demonstrate that these technologies not only improve hybridization success rates but also enhance crop disease resistance and yield potential. Additionally, genomic tools have significantly accelerated the hybrid breeding process and optimized breeding efficiency. Overcoming biological barriers not only improves the efficiency of hybrid wheat breeding but also aids in the development of hybrid varieties with higher yields and enhanced disease resistance under adverse environmental conditions. This is of great significance for ensuring global food security.
