Abstract:

The utilization of heterosis plays an important role in improving wheat yield. Hybrid breeding in wheat is an important development direction for seed production. At present, great progress has been achieved in the strong heterosis combination of hybrid wheat. There are issues such as lack of excellent parents for hybrid combination and hybrid seed production system for high yield and high efficiency wheat, which leads to low seed production efficiency in large area. Therefore, to explore the development of hybrid seed production technology system, germplasm improvement of parental resources and seed production process standards will be conducive to summarizing the overall trend of the development bottleneck and future development direction of hybrid seed production. In this paper, the influencing factors of hybrid breeding in wheat are reviewed. Through the comparison between commercial hybrid crops and superior seed from novel hybrid wheat, some effective suggestions for rapid commercialization of hybrid wheat are put forward, and its future development trend is forecasted.

Key words: hybrid wheat, hybrid seed production, heterosis, precision hill-hole seeding, commercial breeding
