The three lines of hybrid rice breeding, restorer line is to improve the resistance and heterosis of hybrid rice is an important aspect, but also the main direction for the development of hybrid rice over the years. The multipurpose restorer ShuHuang 162 was bred and popularized and applied to meet the need of continuous deepening of hybrid rice. The restorer line was tested with several different types of three-line and dual-purpose nuclear sterile lines, Compared with Restoration Line 64 and Minghui 63, Shuhui 162 not only has stronger restoring ability, but also has great improvement on rice quality and resistance. The results showed that D 162 and Ⅱ You 162, In 1996 and 1997 through the Sichuan Provincial Commission for review and approval, demonstration has been planting more than 200,000 hectares.
